BODMAS describes the order in which arithmetic operations must be carried out.
B = Brackets
O = Order (power or index)
D = Division
M = Multiplication
A = Addition
S = Subtraction.
So 2+3*4
is not to be calculated as 2+3 = 5 and 5*4 = 20
but
3*4 = 12 and 2+12 = 14
BODMAS requires that the multiplication is calculated before the addition.

The BODMAS rule was not discovered: it was invented as a convention. The purpose in setting out the convention was so that calculations were carried out in the same way by different people and at different times.
b= brackets o= over power d= division m= multiplication a = addition s = subtraction
The BODMAS rule, which stands for Brackets, Orders (i.e., powers and roots), Division and Multiplication, Addition and Subtraction, is not attributed to a single inventor. Instead, it is a mnemonic that helps remember the order of operations in mathematics, developed through the evolution of mathematical notation and conventions over centuries. The rule is widely used in many countries to ensure consistent results in calculations.
