Answer:

1. In addition of integers with like signs, both positive and negative signs of the integers will be added and the sign will remain. (positive+positive = add & sign of the answer will be postive, negative+negative = add & sign of the answer will be negative)

In multiplication and division, both postive and negative signs of the integers will be multiplied and divided and the sign of the answer will be postive always {positive/postive=positive & negative/negative=postive, (postive)(positive)=positive & (negative)(negative)=positive}

2.) In subtraction, always keep in mind the "keep, change, change rule" meaning (keep the first sign, opposite the second sign, and opposite the third sign, then perform the rules in addition of integers)

In addition of integers with unlike signs, you will subtract the two numbers, but remember the sign of the answer will depends on the sign of the bigger number that is being subtracted. (Example +2 + -3 = -1).

In multiplication and division of integers with unlike signs, you will multiply them and divide them but remember that the sign of the answer will be negative always
