6,	4	7	2,	9	1	3.	5	8

Example: 7 place: ten thousands

value: 70,000

Example: 6 place: millions

value: 6,000,000

Example: 9 place: hundreds

value: 900

digit: number

expanded form: to show a number as the sum of the value of this digits

Example: 7,965 in expanded form is 7,000+900+60+5

standard form: the usual way of writing a number

Example: 234,908

Example: 400+20+2 in standard form is 422

Example: Fifteen in standard form is 15

word form: to show a number as word(s)

Example: 14,009 in word form is fourteen thousand, nine

Example: 23.19 in word form is twenty-three and nineteen hundredths

Example: 2.9 in word form is two and nine tenths

Operations

sum: answer to an addition problem

addend + addend = sum

addend: numbers that are added together

difference: answer to a subtraction problem

product: answer to a multiplication problem

factor factor = product

factor: numbers that are multiplied

quotient: answer to a division problem

dividend divisor = quotient

dividend: a number to be divided

Example: 45 5 = 9, 45 is the dividend

divisor: the number by which a dividend is divided

Example: 45 5 = 9, 5 is the divisor

Rounding

Rounding to the nearest ten.

23 20 75 80 449 450

39 40 125 130 723 720

Rounding to the nearest hundred.

236 200 754 800 1,492 1,500

391 400 1,258 1,300 1,232 1,200

Rounding to the nearest thousand.

2,363 2,000 7,541 8,000 14,927 15,000

3,915 4,000 12,583 1,3000 12,328 12,000

Rounding to the nearest whole dollar.

$2.31 $2.00 $7.56 $8.00 $44.98 $45.00

$3.92 $4.00 $12.57 $13.00 $72.33 $72.00

Rounding to the nearest ten dollars.

$32.31 $30.00 $79.56 $8.00 $449.98 $450.00

$43.92 $40.00 $127.57 $130.00 $721.93 $72.00

Estimating

estimate the sum: round the numbers and add

23 20 345 300 9,129 9,000

+89 +90 +496 +500 +5,631 +6,000

110 800 15,000

estimate the difference: round the numbers and subtract

45 50 745 700 9,129 9,000

-21 -20 -496 -500 -5,631 -6,000

30 200 3,000

estimate the product: round the numbers and multiply

78 80 67 70 254 300

x 5 x 5 x18 x 20 x 349 x 300

400 1,400 90,000

estimate the quotient: round the numbers and divide

61÷2= 891÷32=

60÷2=30 900÷30=30

Properties of Multiplication

commutative property of multiplication: the order of the factors does not change a product.

Example: 2 4 = 4 2

8 = 8

associative property of multiplication: the way factors are grouped does not change the product.

Example: (2 3) 4 = 2 (3 4)

6 4 = 2 12

24 = 24

multiplicative identity property: any number multiplied by one remains the same number.

Example: 5 1 = 5 or 15 = 5

distributive property of multiplication: multiplying a sum by a number is the same as multiplying each addend by the number and then adding the problem.

Example: 2 (3 + 4) = (2 3) + (2 4)

2 7 = 6 + 8

14 = 14

Example: 432 x 4 = (400 x 4) + (30 x 4) + (2 x 4)

1,728 = 1,600 + 120 + 8

1,728 = 1,728

zero property of multiplication: any number multiplied by zero will result in the product of zero

Example: 5 0 = 0 or 05 = 0
