Hi All,
Does anyone have (or come across) a list of formulae/shortcuts which can be applied when answering questions in the Math section of the GMAT.
Covering areas such as:
Arithmetic progression -
We know that in an A.P, 'l' the last term is given by l = a + (n - 1) * d, where 'a' is the first term, 'n' is the number of terms of the series and 'd' is the common difference.
This can be used when answering the following question:
How many 3 digit positive integers exist that when divided by 7 leave a remainder of 5?
Was wondering whether someone had a list of these type of things, for all the areas of the GMAT Math ?
Thanks.
