Expressions: Going from Written to Numerical

Part 1: Written Expressions to Numerical Expressions 1 Step Operation Get a piece of paper and a pencil and follow along in this video as I teach you about expressions. the sum of 4 and 8 4 + 8 the difference between 8 and 4 8 - 4 The product of 8 and 3 8 x 3 the quotient of 15 and 3 15 ÷ 3 5 less than 9 9 - 5 6 more than 2 6 + 2 Part 2: Written Expressions to Numerical Expressions with 2 Step Operations Continue using your paper and pencil and follow along with the instruction of how to do a 2 Step Operation. 3 times the sum of 4 and 8 3 x (4 + 8) The sum of 3 and 4, subtracted from 8 8 - (3 + 4) The product of 8 and 3, divided by 4 8 x 3 ÷ 4 8 subtracted from the product of 4 and 3 4 x 3 - 8 The difference between 8 and 4, tripled (8 - 4) x 3 Part 3: Sort each operation word(s) and symbols into the correct operation. Addition sum and altogether both in all total add plus + Subtraction difference minus fewer take away left how many more - Multiplication product twice multiply double triple times x Division quotient divide share equally split evenly ÷
