The basics of integers (subtracting and adding)
an integer is a whole number that can be positive or negative. If you are adding integers you would ignore the signs and find the difference. Also to make the answer have the sign of the larger number. For instance -29+15=? it equals 14 and it will take on the sign of the larger number which is a negative., so the answer is -14. If you subtracting integers the rules would be first to change the subtraction sign to addition. Then change the sign of the second number to the opposite. Finally to follow the rules of addition. For example I will use the same equation with subtraction. -29-15=? -29+-15=34 so your answer is 34.
