What is a neat notebook anyway? It’s where you get to sit by the fire with a friend and a hot cocoa to discuss and compare a topic in math. This first topic is the Basic Operations, which are addition, subtraction, multiplication, and division. We’re going to look at the standard algorithm for each of those algorithms and see if we notice any patterns. We’ll also see if we know all the important vocabulary words associated with these algorithms!

- Addend: A number that you add to another number.
- Sum: The answer you get when you add two or more numbers together.
- Minuend: The number you start with when you’re doing subtraction.
- Subtrahend: The number you’re taking away in a subtraction problem.
- Difference: The answer you get when you subtract one number from another.
- Factor: A number that is multiplied by another number.
- Product: The answer you get when you multiply two or more numbers together.
- Dividend: The number that you’re dividing into smaller parts.
- Divisor: The number that you’re using to divide the larger number into smaller parts.
- Quotient: The answer you get when you divide one number by another.
- Standard Algorithm: A step-by-step process for solving math problems.
- Commutative Property: The idea that you can change the order of numbers when you’re adding or multiplying without changing the answer.
- Order of Operations: A rule that tells you which math operations to do first when you have more than one operation in a problem.
- Borrowing: When you need to take a number from the next column over when you’re doing subtraction.
- Place Value: The value of a digit based on its position in a number.
- Remainder: The amount left over after you divide a number into equal parts.
