In mathematics, phrases can be defined as a set of words and numbers that can be arranged properly to form a mathematical expression. Expressions on the other hand have a mathematical operation (addition, division, subtraction, and multiplication) and at least 2 numbers. We use parentheses in math to group things together so that a mathematical operation can be performed within the expression.
