Adding Subtracting Multiplying And Dividing Negative And Positive Numbers – An integer is a positive or negative integer and is zero (all numbers on the number line). Positive means that the number on the number line is to the right of zero. Negative means the number is to the left of zero on the number line. the more you move to the right (or up), the higher your number is. The further to the left (or down), the smaller it is. Negative Positive
Same sign, add sign and keep Different signs, subtract numbers and take sign of larger number * Integer Rules Song* Example: = -8 Example: = -3 Subtraction KCC (keep, change, change) Keep first number, change sign subtract to addition sign and change the sign of the second number. Then follow the addition rules. Example: 4 – (-3) = = 7. Example: 4 – 3 = = 1 * When you subtract rational numbers, you are actually adding the inverse. Multiplication Same signs = positive answer Different signs = negative answer Then multiply/divide as usual Example: (-4)(3) = -12 or -4×3 = -12 Example: -24 ÷ -8 = 3 or -24/ -8 = 3 & division *Every 2 negative values give a positive result! *Parentheses = multiplication *Fraction = division

4 Additive inverse The sum of a number and its opposite is zero. The addition of these two numbers is considered the reverse. For example The addition of -4 is 4 because = 0. If I have $25 in my bank account, the reciprocal of the addition will be -$25.

Other topic guides in this series include:
When multiplying whole numbers, -15 and -3 have the same sign, so the product is positive.
Integer Rules Memorize The Rules.
Using the rule for dividing whole numbers, -72 and -9 have the same sign, so the division is positive.
When multiplying whole numbers, -190 and -10 have the same sign, so the product is positive.
6. A deep-sea diver descends from the surface of the sea at a rate of 10 feet per minute. The diver descends at this rate for 8 minutes, which can be modeled by 8 times (-10) = d, where d is how far below sea level the diver is. How deep did the diver descend after 8 minutes?
