Evaluate. 7-(-19)-18+(-19)+18

Simplify Expression: We start by simplifying the expression using the property that subtracting a negative number is the same as adding its positive counterpart. So, 7 - (-19) becomes 7 + 19. Calculation: 7 + 19 = 26Subtract 18: Next, we subtract 18 from the result obtained in the previous step. Calculation: 26 - 18 = 8Add -19: Now, we add the next term, which is -19, to the current result. Calculation: 8 + (-19) = -11Add 18: Finally, we add 18 to the result obtained in the previous step. Calculation: -11 + 18 = 7
