ASSOCATIVE PROPERTY OF MULTIPLICATION

• That you can group factors in different ways and still get the same product
• 30x24=600
• 24x30=600

COMPATIBLE NUMBERS

• COMPATIBLE NUMBERS ARE EASY TO WORK WITH
• EXAMPLE:estimate 20x19
• 20x24= first we take the 20 then we break it down so we can make the 20 become a 18
• Then we take the 24 and make it a 20.
• Next 20x18=200

COMMUNICATIVE PROPERTY OF MULTIPLICATION

• When the order of two factors is changed the product is the same.
• Example:25x19=245
• 19x25=245

ESTIMATE

• To find an answer that is close to the exact amount
• Example:18x14=
• 18 is close to 20 so we put 20 for the 18
• 14 is close to 10 so the 14 becomes a 10.
• 20x10=200

PARTIAL PRODUCTS

• A method of multiplying in which the ones 1000s and so on or multiplied separately, and the products are added together
• 182×6=600+480+12=1,092
• The answer is 1,092

PRODUCT

• The answer to a multiplication problem
• Example:19x55=545

REGROUP

• To exchange of equal value to rename a number example 50x19= 500 5 hundreds 0 tens 0 ones
