Покрокове пояснення:

Answer 2

Let's solve each expression step by step:

1. 2 * 5 + 6 - 9 * 4

First, perform the multiplications: 2 * 5 = 10 9 * 4 = 36

Now, substitute the results back into the expression: 10 + 6 - 36

Now, perform the additions and subtractions from left to right: 10 + 6 = 16 16 - 36 = -20

So, the result of the first expression is -20.

2. 5 * 8 - 20 + 60 - 50

First, perform the multiplications: 5 * 8 = 40

Now, substitute the result back into the expression: 40 - 20 + 60 - 50

Now, perform the additions and subtractions from left to right: 40 - 20 = 20 20 + 60 = 80 80 - 50 = 30

So, the result of the second expression is 30.

To summarize:

1. 2 * 5 + 6 - 9 * 4 = -20
2. 5 * 8 - 20 + 60 - 50 = 30
