Show answer & explanation
Correct answer: C
Concept: When symbols are missing from an arithmetic expression, evaluate each candidate set using the standard order of operations (BODMAS) — multiplication and division are carried out before addition and subtraction, and operations of the same priority are applied left to right.
Application: Substitute the symbols +, -, x into the given equation and evaluate step by step.
Insert the symbols into 10 _ 98 _ 2 _ 9 to get 10 + 98 - 2 x 9.
Apply BODMAS: multiplication is evaluated first, so 2 x 9 = 18.
The expression reduces to 10 + 98 - 18.
Adding and subtracting left to right: 10 + 98 = 108, then 108 - 18 = 90.
Cross-check: trying any other combination of symbols does not reduce to 90 (for example, multiplying all four numbers together, as in x, x, x, gives a value in the thousands, far larger than 90), confirming +, -, x is the unique fit.
