Question

Write and evaluate an expression that tells you to subtract 6 from 9 then subtract the difference from 12 and then multiply by 3 use at least two types of grouping symbols

Answer 1

Explanation:

One possible expression using two types of grouping symbols is:

3 × [(12 - (9 - 6))]

This expression first subtracts 6 from 9 to get a difference of 3, then subtracts that difference from 12 to get a result of 9. Finally, it multiplies 9 by 3 to get a final answer of 27. The grouping symbols used are parentheses to group the subtraction of 6 from 9, and then another set of parentheses to group the subtraction of that difference from 12. The outermost grouping symbols are the multiplication symbol and the pair of brackets used for clarity.
