Add 5 to p and then double the result is written as (p + 5) x 2 or 2(p + 5).Multiply d by 4 could be written as d x 4 or 4d.Subtract 6 from n could be written as n - 6.When we are generating an expression, we are taking a rule and turning it into algebra.
5(y 2 - 6) = 3y + 8 is another equation.2a + 5 is an expression involving the variable aĪn equation is where an algebraic expression is equal to something, which might be a number, or another algebraic expression.An expression is a mathematical statement where variables and operations are combined.
