Evaluate multi-step numerical expressions using order of operations, including grouping symbols and exponents.
Evaluate without grouping symbols
Problem
Evaluate: \(18~-~3~\times~4~+~6\).
Big Picture
What this problem is really about
This expression is about operation priority, not simply reading from left to right. We’ll complete the multiplication first, rewrite the entire expression with that product in place, and then handle addition and subtraction from left to right. Preserving the untouched operations prevents the structure from changing.
