Worksheet
Order of Operations with Decimals

Where to start inside a single expression is what gets settled. Mixed Multiplication and Division (4 Terms), Chain of Multiplication and Division (Left to Right) and Mixed Operations (3 Terms) carry no parentheses. Calculations with Parentheses, Parentheses with Multiplication and Division (4 Terms) and Two Sets of Parentheses have what is inside the parentheses worked first. Numbers run to one decimal place.

Chain of Multiplication and Division (Left to Right), holding nothing but multiplying and dividing, is worked from the left in order, whereas Mixed Operations (3 Terms) has the multiplying done first. Answers appear where that distinction never took hold and every expression was worked from the left. Have the child hold a finger on the multiplying and dividing and work just those parts again.

Multiplying and Dividing Decimals had one operation to an expression, and this lesson has reached combinations of them. The next unit, Rectangular Prisms and Cubes, leaves calculation to look at the shape of a box and investigate its properties.
