-3
I think one or both of those have to be negative. -3 + 7 = 4 -3 x 7 = -21 3 + -7 = -4 3 x -7 = -21 7 x 3 = 21 7 - 3 = 4 It also works if you subtract.
You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).
2 < 2x + 4 < 18 Subtract 4: -2 < 2x < 14 Divide by 2: -1 < x < 7

4 + 7 + 5 = 16.

1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8
It doesn't actually mean difference, but it can be used to get the difference between values. 11 subtract 4 is 7, and 7 is the difference between 4 and 11.
well, if it is a negative plus a positive, it would be much like subtracting backwards, like this: -4+7=3 or -11+7=-4 also, if it is a positive plus a negative, you subtract 4+(-7)=-3 or 11+(-7)=4
It is: 2 and 1/8 subtract 1 and 7/8 = 1/4
Yes the results is -4 :D
7/12 - 1/4 = 7/12 - 3/12 = 4/12 = 1/3.
