Answer 3

To solve the given expressions step by step:

1. 80 - 16 * 5:

First, we need to perform the multiplication operation, so 16 * 5 = 80. Now, we can substitute this value back into the expression: 80 - 80 = 0.

Therefore, 80 - 16 * 5 = 0.

2. 90 : (6 * 15):

First, we need to perform the multiplication operation, so 6 * 15 = 90. Now, we can substitute this value back into the expression: 90 : 90 = 1.

Therefore, 90 : (6 * 15) = 1.

3. 78 : (13 - 7) * 0:

Inside the parentheses, we need to perform the subtraction operation, so 13 - 7 = 6. Now, we can substitute this value back into the expression: 78 : 6 * 0.

Any number multiplied by 0 is always 0, so 6 * 0 = 0.

Therefore, 78 : (13 - 7) * 0 = 0.

4. 70 + 2 * 12:

First, we need to perform the multiplication operation, so 2 * 12 = 24. Now, we can substitute this value back into the expression: 70 + 24 = 94.

Therefore, 70 + 2 * 12 = 94.

5. 68 : (72 : 18):

Inside the parentheses, we need to perform the division operation, so 72 : 18 = 4. Now, we can substitute this value back into the expression: 68 : 4.

The division operation gives us 17.

Therefore, 68 : (72 : 18) = 17.

6. 64 : (39 - 7) * 1:

Inside the parentheses, we need to perform the subtraction operation, so 39 - 7 = 32. Now, we can substitute this value back into the expression: 64 : 32.

The division operation gives us 2.

Therefore, 64 : (39 - 7) * 1 = 2.

In summary, the solutions to the given expressions are: - 80 - 16 * 5 = 0 - 90 : (6 * 15) = 1 - 78 : (13 - 7) * 0 = 0 - 70 + 2 * 12 = 94 - 68 : (72 : 18) = 17 - 64 : (39 - 7) * 1 = 2
