That refers to terms that have exactly the same combination of variables. For example, in 5xy + x2 - 3xy, the first and last term have the same variables, so they are similar. You can simplify an expression by combining such terms.

The Maths terms combination and permutation apply in chemistry when making the expected industrial calculation.

16x + 16x would be an example of similar terms. Both have corresponding variables (x). The coefficient does not have to be the same for it it have similar terms. Terms are based only on the variable. 16x² + 32x² are similar terms. 16x² + 32x³ are not similar terms.

because there is no mathematical terms in English and maths tends to suck anyway
well in literacy terms it means the way its set out like in a book or something not sure if there is a maths terms one though im not good at maths and I aint kidding
For answer see http://mathsduck.co.uk/
it is across, like the horizon.
