To add two numbers, we simply add their values if they have the same sign or subtract their absolute values if they have opposite signs. Applying this rule, we have:
(-7) + (+1) = -6
Since -7 and +1 have opposite signs, we subtract their absolute values, which are 7 and 1, respectively. The result is -6, which has the same sign as the larger number, -7. Therefore, (-7) + (+1) equals -6.
