Relative Numbers: Addition, Subtraction, Multiplication, Division

Extract

[...] In reality, it is important to well visualized: 19 - 8,6 = 10,4. 19 is greater than one observes the sign before the digit 19: + so the result will be positive: + 10,4 Example 2 to better understand (Negative aspect): To know : The absolute value is 19 and 8,6. In reality, it is important to well visualized: 19 + 8,6 = 10,4. 19 is greater than one observes the sign before the digit 19: - so the result will be negative: - 10,4 Lesson 2 MULTIPLICATION A relative number is a number that can be either positive or negative. [...]

[...] Calculating with relative numbers Lesson ADDITION - SUBTRACTION A relative number is a number that can be either positive or negative. If one adds two positive decimals the result will be systematically positive and the sum will be obtained by adding the two absolute values (That is to say: The absolute value is always positive or zero). Example to better understand: If we add two negative decimals the result will be systematically negative and the sum will be obtained by adding the two absolute values. [...]

[...] To know also, five factors - become Example to better understand: DIVISION A relative number is a number that can be either positive or negative. It's the same principle as multiplication. Division with relative numbers, follows the rules of signs. When dividing two relative numbers of the same sign or : the result will be systematically positive. To know also, four factors - become Example to better understand: When one divides two relative numbers of opposite sign x or x the result will be systematically negative. [...]
