Question

Use brackets to write a mathematical expression for the following statement.

Subtract the difference of $9$and $2$ from the sum of $13$ and $12$.

Answer 1

Formation of an Expression:

Step $1$: Sum of $13$ and $12$

$13+12$

Step $2$: Difference of $9$and $2$

$9-2$

Step $3$: Subtract Step $2$ from Step $1$.

$(13+12)-(9-2)$

Hence, Mathematical expression for the statement $"$Subtract the difference of $9$and $2$ from the sum of $13$ and $12$$"$ is :

$(13+12)-(9-2)$
