Multiplier
A multiplier is the factor that gives a repetition count or scale for another quantity.
What it means
The multiplier answers a “how many times?” or “by what scale?” question. It acts on another quantity. Use the wording and situation to identify that role instead of trusting where the factor is written.
Remember it
Multiplier: the how-many-times or by-what-scale factor.
Example
A photograph is enlarged to 3 times its original width. The multiplier is 3, so an 8 cm width becomes 8 × 3 = 24 cm.
Watch for
A multiplier is not always greater than 1. A multiplier of 1/2 makes a positive quantity half as large.
Common mix-up
Do not decide the multiplier from left or right position alone; the context or stated convention assigns the role.
Exact meaning
A multiplier is a factor that specifies a repetition count or a scale applied to another quantity. In equal-group contexts it often counts the groups, but naming conventions can vary.
