Question

1) – 34 + 67 + (– 19) + (– 44) + 34; 2) 6 + (– 7) – (– 15) – (– 6) – 30; помогите решить премеры

Answer 1

1)-34+67+(-19)+(-44)+34=48
2)6+(-7)-(-15)-(-6)-30=-10

Answer 2

1. To solve the expression -34 + 67 + (-19) + (-44) + 34, you can simply add the numbers together:

-34 + 67 + (-19) + (-44) + 34 = -34 + 34 + 67 + (-19) + (-44)

Since -34 and 34 cancel each other out, you're left with:

0 + 67 + (-19) + (-44) = 67 + (-19) + (-44)

Now, you can add the remaining numbers:

67 + (-19) + (-44) = 67 - 19 - 44

Calculating from left to right:

67 - 19 = 48 48 - 44 = 4

Therefore, the solution is:

-34 + 67 + (-19) + (-44) + 34 = 4

2. To solve the expression 6 + (-7) - (-15) - (-6) - 30, you can follow a similar process:

6 + (-7) - (-15) - (-6) - 30 = 6 - 7 + 15 + 6 - 30

Now, you can simplify the expression by combining like terms:

6 - 7 + 15 + 6 - 30 = (6 + 6) + 15 - 7 - 30

Calculating from left to right:

6 + 6 = 12 12 + 15 = 27 27 - 7 = 20 20 - 30 = -10

Therefore, the solution is:

6 + (-7) - (-15) - (-6) - 30 = -10
