-8 - (-13) = - 8 + 13 = +5 ( minus a minus is a plus)
8 plus 1 times 12 minus 13 is equal to seven.
8/10 + 4/5 = 8/5 or 13/5
It is: 3/8 times 5/6 = 5/16 in its simplest form
It is: (5+13)/6 times 8 = 24
13
-5--3=8 That's (-)by(-)=+ ie -5+13=8
8
13
-5
5 x 3 - 2
(-5)-8=.............(-5)+(-8)=............-13(Negitive Thirteen)
8 + 5 = 13
When you add 8 and 5 the sum will be 13. On the other hand when you add 6 and 7 the sum will be 13. That's why it's equal to 13.
-8
8 goes into 13 once with a remainder of 5.
