24+220

224

2)100-(67+90)

-57

Answer 2

Решение:

24 + (60 + 70) + 90 = 244

1) 60 + 70 = 130

2) 24 + 130 = 154

3) 154 + 90 = 244

100 - (67 + 90) = -57

1) 67 + 90 = 157

2) 100 - 157 = -57

Answer 3

Let's solve the equations step by step:

1. 24 + (60 + 70) + 90

First, solve the parentheses:

24 + 130 + 90

Now, perform addition:

24 + 130 = 154

154 + 90 = 244

So, 24 + (60 + 70) + 90 = 244.

2. 100 - (67 + 90)

First, solve the parentheses:

100 - 157

Now, perform subtraction:

100 - 157 = -57

So, 100 - (67 + 90) = -57.

Thus, the two equations are:

1. 24 + (60 + 70) + 90 = 244
2. 100 - (67 + 90) = -57
