8 = 15 - 7 8 = 8 Yes it is an equation.
It is when you add 1+1 to get 2 then you do 2+2 to get 4 and then do 4+4 to get 8 and so on...
This is the identity property of addition.
Well, honey, 8 can go into 15 a grand total of 1 time. And that's it, no more, no less. So, there you have it, simple math for ya!
You find the most common answer appearingexample:15, 15, 16, 13, 14, 4, 7, 8, 15, 25, 15, 15what is the common appearing number here? 15 is the mode
8 = 15 - 7 8 = 8 Yes it is an equation.
7d-8=7 / 7d=7+8 / 7d=15 / d=15:7 / d=2,14285.....
7+8=15? Answer is 7+7=14

You can tell by looking at them that 5/8 is bigger, since 5 is more than half of 8, and 7 is less than half of 15, but if you want the math... 5/8 = 75/120 7/15 = 56/120 75 is bigger than 56.
16/18 + 15/18 = 31/18 = 1 and 13/18

I Hate ST Math!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Fact: when their is two negative you add meaning if you have -3-5 yo add 3 and 5 then put back the negative sign. therefore (-15-7) = -22
