Concept explainers
When subtraction and addition appear in an expression without parentheses, it is agreed that the operations are performed in order to their appearance from left to right. Taking this into account, and assuming that all expressions are meaningful, use an appropriate real-world model for subtraction to explain why each of the following statements is true.
a.
b.
c.
d.
