Question 1
What is 345 + 232?
Correct answer: A
Add each place: 5 + 2 = 7 ones, 4 + 3 = 7 tens, 3 + 2 = 5 hundreds. The total is 577. The answer 113 comes from subtracting.
-
Question 2
What is 600 - 245?
Correct answer: B
Regroup: 600 is 5 hundreds, 9 tens and 10 ones. 10 - 5 = 5, 9 - 4 = 5, 5 - 2 = 3, so the answer is 355. The answer 445 comes from taking the smaller digit from the bigger digit in each place.
-
Question 3
What is 47 + 38?
Correct answer: B
7 + 8 = 15 ones, which is 1 ten and 5 ones. Then 4 + 3 + 1 = 8 tens. The total is 85. The answer 75 forgets the regrouped ten.
-
Question 4
What is 82 - 29?
Correct answer: C
You cannot take 9 from 2, so regroup: 12 - 9 = 3 ones and 7 - 2 = 5 tens. 82 - 29 = 53. The answer 67 subtracts 2 from 9 instead.
-
Question 5
A school has 268 books in one room and 145 books in another room.
How many books are there in all?
Correct answer: A
268 + 145: 8 + 5 = 13 ones (write 3, carry 1 ten), 6 + 4 + 1 = 11 tens (write 1, carry 1 hundred), 2 + 1 + 1 = 4 hundreds. The total is 413.
-
Question 6
A theater has 500 seats. 326 people are sitting in seats.
How many seats are empty?
Correct answer: D
500 - 326 = 174. Check: 326 + 174 = 500. The answer 826 comes from adding instead of subtracting.
-
Question 7
What is 100 more than 457?
Correct answer: D
100 more adds one hundred: 4 hundreds become 5 hundreds, so 457 becomes 557. The answer 467 is only 10 more.
-
Question 8
What number goes in the box?
35 + ☐ = 90
Correct answer: D
Find the missing part: 90 - 35 = 55. Check: 35 + 55 = 90. The answer 125 adds 35 and 90.
-
Question 9
Kim had 50 beads. She used 18 beads. Then she bought 25 more beads.
How many beads does Kim have now?
Correct answer: C
First subtract: 50 - 18 = 32. Then add: 32 + 25 = 57. The answer 7 subtracts both numbers.
-
Question 10
What is 23 + 14 + 30 + 12?
Correct answer: B
Add the tens: 20 + 10 + 30 + 10 = 70. Add the ones: 3 + 4 + 0 + 2 = 9. The total is 79.
