On simplifying the algebraic expression \( -13a \times -2 \), the answer will be

  • A.−26
  • B.26a
  • C.15a
  • D.−15a

Answer: B

Multiplying two negatives gives a positive.

\[ -13a \times -2 = (13 \times 2)a = 26a \]

The variable \( a \) is carried through unchanged, so the answer keeps it - dropping it would leave the bare number 26.
