Answer :
Final answer:
The solution to the expression 4x(9-2) is 28, following the BIDMAS/BODMAS rule, whereas, the solution to 4x9-2 is 34 because in mathematics the order of operations matters.
Explanation:
This question is about the basic mathematical operation: multiplication and subtraction. In the given expression 4x(9-2), you should first solve the operation inside the brackets (this is known as BIDMAS/BODMAS rule, which stands for Brackets, Indices, Division/Multiplication, Addition/Subtraction). So, 9-2 equals 7. Then, you multiply this result by 4 (4x7), yielding an answer of 28. However, 4x9-2 would be a different problem, you'd first multiply 4x9 to get 36 and then subtract 2 which results in 34. The placement of brackets makes a significant difference in the final outcome in mathematical expressions.
