multiplicand
In multiplication, the number that is multiplied by the multiplier. Technical term used in arithmetic and algebra.
In the expression '3 × 4', 3 is the multiplicand.
Even if you swap the multiplicand and the multiplier, the product is the same.
Compound of 被 (hi, 'receiving' or 'passive' prefix) + 乗数 (jōsū, 'multiplier'), literally 'the number that is multiplied'. The prefix 被- is used in mathematical terms to denote the operand that undergoes an operation.
