**Overview**
The word 'multiply' primarily refers to the mathematical operation of multiplying, where one number is added to itself a specified number of times. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times (3 + 3 + 3 + 3), which equals 12. Beyond mathematics, 'multiply' is used more broadly to describe a rapid increase in the number or amount of something. This can apply to populations, ideas, businesses, or even physical objects.
**Usage Patterns**
As a verb, 'multiply' can be used transitively (taking an object) or intransitively (without an object). Transitively, it often appears with 'by' to indicate the factor of increase or the operation being performed. For example, “The bacteria multiplied by ten overnight.” Intransitively, it signifies a general increase. For instance, “The rabbits began to multiply in the fields.” It's commonly used in contexts discussing growth, expansion, and reproduction.
**Common Contexts**
You'll frequently encounter 'multiply' in educational settings, especially in math classes. In science, it's used to describe population growth (e.g., bacteria, cells) or the spread of something. In business, it can refer to expanding operations or increasing profits. In everyday language, it might describe how quickly something has become more numerous, like “The opportunities seemed to multiply after she got the promotion.”
**Similar Words Comparison**:
- Increase: A more general term for becoming or making larger. 'Multiply' implies a more significant or rapid increase, often through a process of reproduction or repeated addition.
- Grow: Similar to 'increase', but often suggests a natural, organic development. 'Multiply' can be more about a rapid surge in numbers.
- Expand: Focuses on increasing in size, scope, or extent. While related to an increase in quantity, 'expand' doesn't always mean a rise in the number of individual units.
- Reproduce: Specifically relates to the biological process of creating offspring, leading to an increase in population. 'Multiply' is a broader term that can encompass reproduction but also other forms of numerical growth.
使い方のコツ

The context usually makes the meaning clear. Be mindful of the distinction between the precise mathematical term and its broader figurative use.
よくある間違い
Avoid using 'multiply' when a simple 'increase' or 'add' would suffice, as 'multiply' suggests a significant or rapid rise. Also, ensure correct prepositions are used, like 'multiply by X' for the mathematical operation.
