5.3 Whole Number flashcards

Flashcards covering whole number vocabulary, standard algorithms for multiplication and division, area models, and time measurement constants.

Product

The answer when you multiply two or more numbers together.

Inverse Operations

Mathematical operations that undo each other, specifically Multiplication and Division.

Days in a month

$30$ days per month ($30.436/\text{month}$).

Days in a year

$365$ days per year ($365.25/\text{year}$).

Multiplication Diagrams (area models)

A picture that helps you break a big multiplication problem into smaller, easier parts by splitting numbers into tens and ones, multiplying inside smaller boxes, and adding all partial products together.

Standard Algorithm (Multiplication) Step 1

Estimate the result of the multiplication, such as rounding $1,287 \times 365$ to $1,000 \times 400$ to get $400,000$.

Partial Products

The middle steps in the standard multiplication algorithm where you multiply the top number by the ones, tens, and hundreds places of the bottom number before adding them together.

Quotient

The answer to a division problem, which is placed above the division bracket starting at the place value determined by the initial estimate.

Standard Algorithm (Division) Steps

A repetitive process used to solve division problems consisting of: Divide, Multiply, Subtract, and Check.

Remainder

The amount left over at the end of a division problem that cannot be shared among groups, such as the $2$ remaining in the problem $560 \div 18 \rightarrow 31\,r2$.
