Question

How do you use numerical expressions to solve real-world problems?

Answer 1

Determine how real-world problems can be solved by using numerical expressions.

The real-world problems can be solved by using the numerical expression if we can convert them into an algebraic expression.

For example:

Consider that $x$ represents the fixed monthly salary and expenses are $a,b\mathrm{and}c$, then savings is the difference between fixed monthly salary and expenses.

Therefore, the real-world problem can be solved to convert them into algebraic expressions.
