Order of Operations: First, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMDAS. Since there are no parentheses or exponents in this problem, we start with multiplication.Calculate 6×4.6×4=24
Multiplication: Next, we subtract 3 from the result of the multiplication.Subtract 3 from 24.24−3=21
