Father Bidmas and the order of operations in an equation.

BIDMAS

Equations can be scary,
and really look quite tough,
Let BIDMAS be a helping hand,
To guide you through that stuff.

B, it stands for Brackets,
(Brackets of any sort),
Within which you find numbers,
And algebra are caught.

I, it stands for Indices,
Things like powers and roots,
Cubes and squares and other powers,
