Answer 2

SOLUTION

TO DETERMINE

Put one set of brackets in this calculation so that it is correct. 10 – 3 × 4 – 2 + 1 = 5

EVALUATION

Here

LHS = 10 – 3 × 4 – 2 + 1

RHS = 5

If we put one set of brackets in this calculation as below 10 - 3 × ( 4 - 2 ) + 1

Then we get

LHS

= 10 - 3 × ( 4 - 2 ) + 1

= 10 - 3 × 2 + 1

= 10 - 6 + 1

= 4 + 1

= 5

= RHS

Hence the equation is now valid

FINAL ANSWER

Hence the required expression is

10 - 3 × ( 4 - 2 ) + 1 = 5
