# Thread: math equations in English

1. ## math equations in English

3 x 6 = 18

1) Three times six equals (to) eighteen.

2) Three multiplied by six is equal to eighteen.

3) Three multiply with six is equal to eighteen.

I think the first two examples are correct and common. What about the third one? Is it correct? Is 'with' neccessary? Also, why is 'multiply' in a plural agreement instead of in a singular form, which is multiplies?

When it comes to division, people usually say ' X divided by Y equals to Z'. However, sometimes I hear people always say ' X divide by Y equals to Z'. Is it grammatically correct?

Omit 'to'

Three times six equals eighteen.

Three multiplied by (not with and not equal to) six is eighteen.

'equals to' verb phrase can not be used in this sense

I do not think he equals to the task.

Thanks for ur reply. I wonder why 'equals' can be used in the first example but not the second.

Btw, is the following sentence correct?
' X divide by Y equals to Z'. Must it be 'divided'?

"Must it be 'divided'?" Yes.
'Equals' and 'is' are interchangeable.

Thanks for ur quick reply. I understand that 'equals' and 'is' is interchangeable, however, it boggles my mind that why u said 'equals' cant be used in the second example.
I got the following example in a dictionary. Then how would u explain 'equals' can be applied here?

10 divided by 5 is/equals 2.

"Thanks for ur quick reply. I understand that 'equals' and 'is'( is) ARE interchangeable, however, it boggles my mind (that) why u said 'equals' cant be used in the second example."

I never said that.
Just because I wrote the 2nd sentence using 'is' it does not follow 'equals' would be ill-used there in my opinion.

Hi. One more question.

5 + 3 = 8

I think the most common way to say is ' five plus three is equal to eight', right?
Another way to say with 'add':

five add to three is eight.
or
three add to five is eight.

Which one is correct to the corresponding equation above?

10. ## Re: math equations in English

Real numbers are associative under addition, which means the term order may be inverted: 1+2=2+1.

"five added to three is eight.
or
three added to five is eight."

Or, five plus three is ... .
