The sum of ten and the quotient of a number x and 6
White raven [17]

Hey!


Let's simplifythe expression:


"Sum" is a term used to add. In this expression, you will be adding


"Quotient" is a term used to divide. In this case, you will be dividing x(a number) and 6


Quotient of a number and 6 = x ÷ 6


That gives you: 10 + (x ÷ 6)


10 + (x \div 6)
