Final answer:
Samantha's remaining debt is $1.50
Step-by-step explanation:
"Arithmetic" typically refers to the branch of mathematics that deals with the properties and manipulation of numbers, especially the basic operations of addition, subtraction, multiplication, and division.
The expression for Samantha's remaining debt can be found by subtracting the amount she paid her dad from the amount she owes him. So, $7.00 - $5.50 = $1.50.
Understanding arithmetic is fundamental to higher branches of mathematics and is essential for everyday mathematical applications. It forms the basis for more advanced topics like algebra, calculus, and beyond.
