There are conventions about the order of operations to try to resolve this, sometimes called BODMAS
in UK schools.

Therefore, six items included two expanded items were designed based on students' knowledge of BODMAS rule.
Students conjoined the algebraic terms in the bracket by misapplying the BODMAS rule of arithmetic in algebra.
Incorrect order of operations errors occurred because students did not apply the BODMAS rule in algebraic expressions involving multiplication.
Incorrect order of operations error occurred as students simplified algebraic expressions from the 'left-to-right' order without considering the priority of operations in arithmetic (BODMAS rule).
They were confused between the multiplication and the addition of variables and did not apply the BODMAS rule when simplified algebraic expressions involving multiplication.
. The Australian Mathematics Teacher, 65(3), 20-21.
Students should be told that the spreadsheet calculations in Excel use BODMAS, and therefore the answer given will be 37 since the multiplication is to be performed first of all.
but are unnecessary because of BODMAS. However the overuse of brackets should not be discouraged as this frequently helps students in many complicated operational problems.
Here are some fun and creative exercises that you could use with your students to help them develop competence with BODMAS.
Use exactly two twos (2) and any BODMAS operations to make as many different numerals as possible.
