Example 12: Mixed Algebra Review

Step-by-step worked example for this lesson track.

Problem

Evaluate 3+−10⋅4−−5\text{Evaluate }3+-10\cdot4--5

1. Recognize Pattern

a+b⋅d−c⇒a+(bd)−ca+b\cdot d-c\Rightarrow a+(bd)-c

2. Apply Method

5+10⋅2−4=215+10\cdot2-4=21

3. Conclude

3+(−10⋅4)−−5=−323+(-10\cdot4)--5=-32

Final answer

3+(−10⋅4)−−5=−323+(-10\cdot4)--5=-32
