What is bodmas?

Answer 1

BODMAS is an acronym for helping remember the order for dealing with mathematical operators in a mathematical statement (operators are done according to the letters of the word from left to right):

B - Stands for Bracket.

O - Stands for "OF" or "Orders" (i.e. Powers and Square Roots, etc.)

D - Stands for Division.

M - Stands for Multiplication.

A - Stands for Addition.

S - Stands for Subtraction

Note that the acronym is not totally correct if obeyed strictly: 1 - 2 + 3 gives -4 using BODMAS (as it says do the addition before the subtraction), but the correct value is 2.

The fact is that there are two pairs of operators that have equal precedence and should be done in left to right order: Divide and Multiply, Subtract and Add. (Alternatively, if Divide and Subtract have a slightly higher priority in their pair and are done first, then the answer will always be correct, ie the acronym should be BODMSA.)

1-2=-1

-1+3=2

Nothing wrong with BODMAS
