If a equals 3 and b equals minus 5 then a minus b equals what
÷/÷ = +
a minus take away a minus makes a minus
-7
a - b = c -(a - b) = -c b - a = -c
Anything minus itself equals zero.
If a equals 3 and b equals minus 5 then a minus b equals what
(15/2 minus 5/8) becomes (60/8 minus 5/8) by finding the common denominator of the two fractions. By using the laws of subtracting fractions, 60 minus 5 equals 55, and the denominator remains the same, 8. So, the answer is 55/8, or 6.875.
x=-1 ^ how do you know?
The same way as now (minus the calculators.) The problems were the same, adding, subtracting, division, multiplication, exponets, subsets, etc.
What do you mean by "and" ? If multiplication or division, the result is negative. If addition or subtraction, the sign of the result depends on which one is bigger.
To subtract fractions, you need a common denominator. In this case, the common denominator is 7. So, 8/14 is equivalent to 4/7. Subtracting these fractions gives us 0. Hence, 4/7 minus 8/14 equals 0.

203 minus 76 equals 127.
120 minus 87 equals 33.
