# Is "multiply to" correct?

Can I write "A is multiplied to B"?

The general sentence is "B is multiplied by A", which has the same meaning above.

I could not find any example in the internet, Thanks.

"A multiplied to B" is incorrect. When discussing the multiplication of two numbers, we say the first number is multiplied by the second number.

Here are the common arithmetic operations:

`A + B` - B is added to A
`A - B` - B is subtracted from A
`A x B` - A is multiplied by B
`A ÷ B` - A is divided by B
`A / B` - A is divided by B (often seen e.g. in computer code, spreadsheets, etc)

I have no idea why there are different prepositions used for addition and multiplication because they are both commutative operations, but that is what is idiomatic.

Multiply three by five.

Fortunately, you really only need to learn the prepositions for the non-commutative operations of subtraction ("from") and division ("by" or "into").

It is idiomatic (and mathematically sensible) to say
