121.2 - 1.212 + 12.12

The correct answer is Option (2) → 132.108

Subtraction and addition are done from left to right, with the decimal points lined up (121.2 written as 121.200 and 12.12 as 12.120, so every number has three decimal places).

• Subtracting first: \(121.200-1.212=119.988\)

• Then adding 12.12: \(119.988+12.120=132.108\)
