You Can Often Use Google To Find The Meaning Of A Maths Word

Type or paste the word into Google and sometimes you can see that the explanation is in one of the results.
Examples might be quadrilateral , cone and cosine

But sometimes you type in a word and the search results do not seem to be relevant.
An example might be even - the results may show nothing to do with the meaning of an even number
So search with even number or number even or maths number even

SOMETIMES YOU NEED TO LOOK DOWN THE LIST OF RESULTS
