what number is in the tens place?

2539

3
100

363 decomposed is what

300 + 60 + 3

100

true or false

when we adjust addition problems, we add different numbers to both sides

false

we add to one side and subtract the same number from the other side


100

true or false

grouping is when we add 3 numbers together at the same time

false

it is when we have 3 numbers and we add two first and then the 3rd

200

what place is 3 in?

3575

thousands

decompose this equation 

632 + 315

632 + 315 = 

600 + 300 = 900

30 + 10 = 40

2 + 5 = 7 

900 +40 + 7 = 947

200

true or false

when we adjust for subtraction, we can either add or subtract the same number from both sides

true 

200

solve this by grouping

367 + 323 + 643 = 

367 + 323 + 643 = 

690 + 643 = 1333

adjust this equation

356 + 785 = 

356 + 785 =

 +4     -4

360 + 781 = 1141

300

solve this equation by grouping

569 + 425 + 646 = 


569 + 425 + 646 = 

994 + 646 = 1640

400

tell me this number in standard and expanded form


two thousand six hundred twenty five

standard: 2625

expanded: 2000 + 600 + 20 + 5

400

decompose this equation

689 - 315 = ? 

689 - 315 = 

689 - 300 = 389

389 - 10 = 379

379 - 5 = 374

400

adjust this equation by adding 

879 - 233 =

879 - 233 =

+1     +1

880 - 234 = 646

400

was this grouped correctly?

742 + 120 + 142

662 + 142 = 804

yes
500

true or false, 5639 in expanded form is 

five thousand six hundred thirty nine

false 

it is 5000 + 600 + 30 + 9 

500

decompose this equation the difficult way 

642  - 255 = 

642 - 255 = 

642 - 242 = 400

400 - 10 = 390

390 - 3 = 387
