complete to show how you can find the sum by making a ten, hundred, or thousand.

9+5=14
9+1+ blank
10+ blank
blank

90+50=140
90+10+blank
100+blank
blank

900+500=1400
900+100+blank
1000+blank
blank

9+5=14

9+1+4
10+4
14
same thing on the others, just add zeros

how do u do it

800+500=

800+500= 1,300

800+200+300
1000+300
1,300

To find the missing numbers, we can use the strategy of making a ten, hundred, or thousand.

For the equation 9 + 1 + blank, we need to find the number that, when added to 9 and 1, makes a ten. Since 9 + 1 is already 10, the answer is 0.

For the equation 10 + blank, we need to find the number that, when added to 10, gives another multiple of 10. So the answer is 0.

For the equation 90 + 10 + blank, we need to find the number that, when added to 90 and 10, makes another multiple of 10. Therefore, the answer is 0.

For the equation 100 + blank, we need to find the number that, when added to 100, gives another multiple of 100. So the answer is 0.

For the equation 900 + 100 + blank, we need to find the number that, when added to 900 and 100, makes another multiple of 100. Therefore, the answer is 0.

For 1000 + blank, we need to find the number that, when added to 1000, gives another multiple of 1000. The answer is 0.

So the missing numbers in each case are 0.
