Objective At the end of this lesson, students should be able to Calculate with standard form. Calculations involving very large or very small numbers can be done more easily using standard form. Example 1 Multiply the following and write your answer in standard form a) 600 × 4000 b) (2.4 × 104) …
Objectives At the end of this lesson, students should be able to: Use the standard form A × 10n where n is a positive or negative integer and 1 < A < 10 Change numbers into standard form and vice versa A negative index is used when writing a number between 0 and 1 in …
Objectives At the end of this lesson, students should be able to: Use the standard form A × 10n where n is a positive or negative integer and 1 < A < 10 Change numbers into standard form and vice versa Standard form is also known as standard index form or sometimes as scientific notation. …
Objective At the end of the lesson, students should be able to: Obtain appropriate upper and lower bounds to solutions of simple problems given data to a specified accuracy. We can obtain appropriate upper and lower bounds to solutions of simple problems like the calculation of the perimeter or the area of a rectangle given …

Objectives At the end of the lesson, students should be able to: Give appropriate upper and lower bounds for data to a specified accuracy. Use upper and lower bounds for calculations. When rounded values are used for calculations, we can find the upper and lower bounds for the results of the calculations. Addition and multiplication …

Objectives At the end of the lesson, students should be able to: Give appropriate upper and lower bounds for data to a specified accuracy. Numbers can be written to different degrees of accuracy. For example, 3.5 ,3.50 and 3.500 appear to be the same but they are not the same because they are written to …
Objective At the end of the lesson, students should be able to: Estimate answers to calculations. Sometimes the calculations carried out using a calculator give answers that are not whole numbers. A calculator will give the answer to as many decimal places as it will fit on the screen. Answers should not be given to …
Objective At the end of the lesson, students should be able to give approximations to specified numbers of significant figures (S.F). Numbers can also be approximated to a given number of significant figures (sf). We often use significant figures (sf) when we want to approximate a number with a lot of digits in it. In …

Objective At the end of the lesson, students should be able to: Give approximations to specified decimal places (D.P) A number can be approximated to a given number of decimal places (dp). When a number is written in decimal form, the digits to the right of the decimal point are called decimal places. This also …
