Math 4th grade Week 3

if three or more factors are multiplied, they can be grouped in any order, and the product will remain the same; a × b × c = (a × b) × c = a × (b × c)

• Rounding

• Equation

if multiplying a number by a sum of numbers, the product will be the same as multiplying the number by each addend and then adding the products together; a × (b + c) = (a × b) + (a × c)
