Adding 25 + 13 Adding is the opposite of subtracting. Taking 25 + 13, you have to reduce the problem to 215 your answer.

Adding 25 + 13 Now i have equalled up the squares. My answer is 38 and I got that by adding up but nominator and dominator and together I get 38.

Subtracting 34 – 13 Subtracting is the opposite of adding. Try finding a common denominator. 4 x 3 = 12 and the bring the 12 down under the 34 and the 13 and put a line over it.

Subtracting 34 – 13 Taking the 12 and trying to find what goes into 3 which is nine and then what goes into 4 is one. And then try and take 4 for see what goes in to it 3.
