find the value of the expression 3*45 divide 9-2 (10-6) -4 divide 2

If you mean

3*45/9 - 2(10-6) - 4/2

that would be

3*5 - 2(4) - 2
= 15 - 8 - 2
= 5

If not, use parens to disambiguate

To find the value of the expression 3 * 45 ÷ 9 - 2(10 - 6) - 4 ÷ 2, we follow the order of operations (also known as PEMDAS/BODMAS).

1. First, we evaluate within the parentheses: 10 - 6 = 4.
The expression becomes: 3 * 45 ÷ 9 - 2(4) - 4 ÷ 2.

2. Next, we perform the multiplication and division from left to right:
3 * 45 = 135
135 ÷ 9 = 15
The expression becomes: 15 - 2(4) - 4 ÷ 2.

3. Then, we perform the multiplication within the parentheses:
2(4) = 8
The expression becomes: 15 - 8 - 4 ÷ 2.

4. Finally, we carry out the remaining subtraction and division:
15 - 8 = 7
4 ÷ 2 = 2
The expression becomes: 7 - 2.

Therefore, the value of the expression 3 * 45 ÷ 9 - 2(10 - 6) - 4 ÷ 2 is 7 - 2, which equals 5.
