Question

20+(40+15)-21 14+6(23-3)

Answer 1

20+(40+15)-21 = 20 + 55 - 21 = 54
14+6(23-3) = 14 + 6(20) = 14 + 120 = 134

Answer 2

Let's evaluate each of these expressions:

1. 20+(40+15)-21

We start by simplifying the expression within the parentheses first, which is 40+15 = 55. Then, we substitute this value back into the original expression to get:

20 + 55 - 21

Next, we perform addition and subtraction from left to right:

= 75 - 21

= 54

Therefore, 20+(40+15)-21 evaluates to 54.

2. 14+6(23-3)

Here, we need to simplify the expression within the parentheses first, which is 23-3 = 20. Then, we substitute this value back into the original expression to get:

14 + 6(20)

Next, we perform multiplication and addition from left to right:

= 14 + 120

= 134

Therefore, 14+6(23-3) evaluates to 134.
