One way to look at this is to use a number line. Numbers to the right on a number line are greater (more) than numbers to the left. For example 3 is to the right of, and greater than 2. Similarly, zero is to the right and greater than -1. So which number is more to the right, negative 7 or 6. If we interpret your question as is -7 or-6 greater, then we can see that -6 is to the right of -7 (closer to approaching zero), so -6 is "more" than -7.
-6 - -7 = -6 + 7 = 7 - 6 = 1.
0.8571
-1.5 would be -9/6, which is more negative or less than -7/6; so the bigger one is -7/6
-7+(-6)= -7-6= -13
6 times -7 is -42
Positive six: 6 or +6.
6
It is -6--7 = 1
Negative 6 minus 7 is Minus 13!
-6 + 7 = 1.
-6 is greater than -7
-3 + -7 + 5 + -4 + -6 = -15
