-52 (Negative X Negative = Positive) (Negative X Positive = Negative)
(+)13 does NOT equal (-13). However, their modulii (plural of modulus) are equal at '13' . It is written as as a value -13 < +13 However the modulii is written as |-13| = |+13| note the use of vertical lines, because the numerical value is the same.
The value of the positive number is greater than the value of the negative number. 23 + (-13) = 10 but (-23) + 13 = (-10)
positive 169
7-(-13) also equals: 7+13. Because, if you look at it, you can see that -(- can look like a positive. This is because taking negative from a negative can be considered adding! Isn't this unique?

It depends. (a) a positive minus a smaller positive is positive, (b) a positive minus a positive of the same size is zero, and (c) a positive minus a bigger positive is negative. For example, (a) 8 - 6 = 2 (b) 8 - 8 = 0 (c) 8 - 11 = -3
The sum of a positive number and a negative number can be either negative or positive. 9 + -3 = 6 9 + -13 = -4
a negative minus a positive is a negative ex: -12-13=-25 -9-2=-11 -100-1=-101
Adding two negatives will make a larger negative sum. but adding a larger positive to a smaller negative will give a positive sum. -45 + 58 = 13
