2^5(5-6)+9Ă· 3 For this expression, the expression inside the parentheses should be evaluated first, followed by calculating the exponents, followed by multiplication and division, then finally addition.

Operation Before Simplification After Simplification
Subtract term 2^5( 5- 6)+9Ă· 3 2^5( -1)+9Ă· 3
Calculate power 2^5(-1)+9Ă· 3 32(-1)+9Ă· 3
Multiply 32( -1)+9Ă· 3 -32+9Ă· 3
Calculate quotient -32+ 9Ă· 3 -32+ 3
Add terms -32+ 3 -29
The expression equals -29.
