Solve 8+5-6×(2+1)+7: Order of Operations Practice

To solve this expression, we need to follow the order of operations: Parentheses, Exponents (not in this problem), Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Start with the parentheses: $(2+1) = 3$

Substitute back into the expression: $8+5-6\times3+7$

Then, perform the multiplication: $6\times3 = 18$

Substitute back into the expression: $8+5-18+7$

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

$8+5 = 13$

Then: $13-18 = -5$

Finally: $-5+7 = 2$

So, the final answer is $2$.
