Is 60÷5(7-5)=24 correct?
Answer: No, 60÷5(7-5)=24 is not correct. The reason for this is that the order of operations
was not followed properly.
According to the order of operations, multiplication and division should be done before
addition and subtraction. Within multiplication and division, calculations should be done from
left to right regardless of which operation comes first.
Applying these principles to the expression, we start with the parentheses: (7-5)=2. Then, we
have to perform the division 60 ÷ 5, which gives us 12. Finally, we have to multiply 12 by 2,
which gives us 24. Therefore, the correct equation is 60÷5(7-5)=12x2=24.
In the original equation, the multiplication symbol was omitted, leading to confusion about
the order of operations. If we interpret the expression as 60 divided by 5 times (7-5), we end
up with 60 divided by 5 times 2, which is equal to 24. However, if we interpret the expression
as 60 divided by (5 times 7) minus 5, we end up with a different result: 60 divided by 35,
which simplifies to 12/7. Therefore, it is important to use parentheses and correctly follow the
order of operations to avoid errors in math equations.
