In engineering studies, working with numbers is one of the most substantial concepts. Numbers are not used only in civil or architecture engineering as most of people think. Numbers are important in all engineering disciplines. For example, agriculture engineers work in numbers in there calculation to design systems that produce food, feed, fiber and other products with high quality. Also, in computer engineering field, computer engineers must know how to deal with numbers because computer language based on numbers. For this reason, this section will describe the mechanisms of using numbers in a proper way.
• Numbers notation is a way that scientist used to reformat numbers especially, very large numbers and vary small numbers. Numbers notation has many useful properties, so it used by scientist, mathematicians, and engineers. (a x 10^b) is the form of all numbers written in scientific notation ,where b is an integer number , and a is real number . Also, we can read as 'a' times 10 raised to power b. However, any number can be written in scientific notation (ax10) .for any number greater than 1 the exponent b is positive. Otherwise, when number between 0 & 1 the exponent b is negative and it can be written as ( ax10^-b). For example 0.0015 can be written as .5 x 10^-3.

When performing a mathematical calculation, it is important to pay attention to accuracy. Suppose you are asked to measure the width of a standard piece of paper such as a page in this research . The
teacher I am required to take into account both dimensions. So this became my goal and tool to use.
Each logarithm has two parts, the characteristic and the mantissa. These are based on the exponential power that is with the base number. For example, 10^4, we would be looking at the 4, which is the exponent. The characteristic is the exponent of the base (4). The mantissa is the number(s) after the decimal point of the exponent. This example is an exact multiple of 10 so the numbers after the decimal will always be zero. So in simpler terms, the characteristic and mantissa are divided by the decimal point, characteristic is on the left and the mantissa is on the right-of the decimal
Originally, the exponent notation was not used, but was a further developed method to explain Burgi’s concept. In conclusion, Burgi’s discovery of relating geometric and arithmetic series is the reason why he has a great contributor to the development of logarithms.
Look at the calibration marks on your ruler to determine the degree of uncertainty and number of significant figures that can be made when measuring with a ruler.
of contexts, checking their answers in different ways, moving on to using more formal methods of working and recording when they are developmentally ready. They explore, estimate and solve real-life problems in both the indoor and outdoor
John wants to know the values of the area and perimeter of a rectangle. John can take measurements of the length and width of the rectangle in inches. John's measurements are expected to be accurate to within 0.1 inch.
[Using addition, students’ will be able to decompose numbers totaling 8,9,10 when a part of the whole is provided in a number bond]
We can use this information for simple division, multiplication and even when multiplying and dividing larger numbers. This information can be used when cooking, grocery shopping, building things etc..
The book Super Crunchers: Why Thinking-by-Numbers is the New Way describes how number crunching affects your live in so many different ways. Number crunchers are people who use data to try to predict specific outcomes such as what conditions will create a legendary vintage of wine. A super cruncher is a new breed of number cruncher who analyzes massive datasets to discover correlations between unrelated things such as poor credit scores and the likelihood of getting into an accident. The super crunching has made it easier to find correlations between random unrelated pieces of data. With the advancement of technology, companies are able to store massive databases full of data an example would be Google that has about four petabytes of stored data for crunching. Super crunching helps businesses to increase their efficiency by knowing how to strategically place products in their stores.
The chapter illustrates the connection between math and language by expressing the explicit differences between two cultures. He compares the brevity of Chinese numbers to those of English numbers. For example, the words for Chinese numbers are most likely monosyllabic, resulting in a lesser time to say and process them. The number seven in the Cantonese dialect of Chinese is pronounced as “qi” (Gladwell). This brief number system can be beneficial to toddlers and children learning how to speak and perform simple mathematical functions. A child will better process numbers in the Chinese number system rather than those of the English number system, and early learning can help a child’s brain grow more rapidly as the child grows older. The Chinese language can be seen as advantageous because it helps with processing the number system. This connection between language and math can be seen in other real-world situations, as
Logarithms are used more commonly in everyday life than you think. Using logarithms is an easier way to describe numbers in powers of ten, such as if we are using terms like interest rate or double digits. The author thinks it is important that they are the cause for an effect and the shared “effect” is seeing something develop and become larger. From the article about Using Logarithms in the Real World, “logarithms find a plausible cause for that effect and puts numbers on a human-friendly scale” (2). They describe changes in terms of multiplication and when dealing with a series of multiplications, logarithms help count them. An easier way to think of them is that it says how many of one number you need to multiply to get another number. Logarithms show up in everyday life in six-figure salaries or two-digit expenses where we describe numbers in terms of their digits. Logarithms are none the less extremely important
In 498 AD, the Indian (Hindu) mathematician and astronomer Aryabhatta introduced the decimal system when he stated, “Sthanam sthanam dasha gunam.” This statement means, “place to place in ten times in value.” This may have been the origin of the modern ten-based decimal value system used today.
The purpose of my task is to compare daily website traffic to the daily sales conversion rate over the month of June for a newly established sales campaign. With this information I can identify whether the projected conversion rate percentage has been forecast accurately. This information will also be used as the control sample data to base future sale trends on.
Purpose: The purpose of this experiment is to understand data analysis through measuring and calculating different values. These values include length, diameter, circumference, volume, and the percent error. Introduction: This experiment helps students understand data analysis such as units, conversions, error types and calculation, accuracy, and precision by requiring the students to measure a pipe using calipers, string, and a meter stick.
In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.
