7
-5 + +7 = -5 + 7 = +2 = 2
12
-2
6 + 5 + -4 = 7
Two negatives become a positive. 5 - 7 - 1 = -3
2
no not always. as long as the first number is bigger than the second number. if it is not, the answer is negative. 7-5=2 5-7= -2
1 2 3 4 5 6 and 7 are the first 7 positive #s
-3
There are an infinite number of positive integers divisible by 3, 5, and 7. This is because there is no limit to numbers and they go on indefinitely in both a positive and a negative direction.
Either one. 5 + (-7) = -2 5 + (-2) = 3 You can even get zero: 5 + (-5) = 0
