Saxon Course 2: Lesson 11

​Example: In the morning, the trip odometer in Mrs. Candy's car read 47 miles. At the end of the day the trip odometer read 114 miles. How many miles did Mrs. Candy drive that day?

• We can set up the word problem as an equation: 47 + x = 114

• Now we solve for x. 114 - 47 = 67

• We can say Mrs. Candy drove 67 miles!

​Combining = Addition

​Example: Tim baked 4 dozen muffins. He made a platter with some of the muffins and gave them away at school. He had 32 muffins left when school was over. How many muffins did Tim give away?

• We can set up the word problem as an equation: 48 - x = 32

• Now we solve for x. 48 - 32 = 16

• We can say Tim gave away 16 muffins!

​Separating = Subtraction
