Which mathematical expression is equivalent to the number sentence below multiply 8 by 12, and then add 9

Solution :

It says multiply 8 by 12 and then add 9

reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .

Let us first write multiplying 8 and 12 which makes it 8 x 12

the result is being add to 12 so we place 8x12 in parenthesis then add 12

which , makes it : ( 8x12) + 9

this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .

we can write it without parenthesis like : 8x12 +9

Answer is third option .
