Question

-(+18)= +(-4)= -6+(-7)= -13-(-19)=

Answer 1

1)-18 2)4 3)-13 4)-6 правильный ответ

Answer 2

Let's solve each of these arithmetic expressions step by step:

1. -(+18): The negative sign in front of a positive number changes its sign to negative. So, -(+18) is equal to -18.

2. +(-4): The positive sign in front of a negative number doesn't change its sign. So, +(-4) remains as -4.

3. -6 + (-7): When adding two negative numbers, we simply add their absolute values and keep the negative sign. So, -6 + (-7) is equal to -13.

4. -13 - (-19): Subtracting a negative number is the same as adding its positive counterpart. So, -13 - (-19) becomes -13 + 19. Subtracting a larger number from a smaller number results in a negative answer. So, -13 + 19 is equal to 6.

Therefore: -(+18) = -18 +(-4) = -4 -6 + (-7) = -13 -13 - (-19) = 6
