In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression.. For example, in mathematics and most computer languages, multiplication is granted a higher precedence than addition, and it has been this way since the FYI: The traditional sequence of grouping symbols, working from the inside out, is "parentheses", then "square brackets", and then "curly braces"; then you repeat the sequence, as necessary. But this is not, to my knowledge, a rule; it's just a common convention.

a − (b − c + d) = a − b + c − d. The parentheses can be omitted if the input is a single numerical variable or constant (as in the case of sin x = sin(x) and sin π = sin(π). [a] Another shortcut convention that is sometimes used is when the input is monomial ; thus, sin 3 x = sin(3 x ) rather than (sin(3)) x , but sin x + y = sin( x ) + y , because x + y is not a monomial.
