My Numbers

I picked the numbers .11, 2/5, -10, -7. I picked two negative numbers and two positive numbers. There is one decimal number. There is one fraction number.

Comparing

-10 < -7

-7 is closer to 0 so it it the larger number.

Addition

subtraction

-10 + 6 = -4

2/5 + 3/5 = 5/5 = 1 whole

when you have addition and one number is a negative (-) you have to subtract, but if they're both positive the add them like usual.

.11 - 5 = .6

-7 - (-2) = -5

When you have a subtraction problem you have to add a line and change the sign, so if its negative (-) then you change it into a positive, if its a positive (+) change it to a negative.
