1. A fish tank has 3879 fishes. Another fish tank has 2836 fishes. What is the difference between the number of fishes in the two fish tanks?

Step 1: Subtract the ones.

9 ones − 6 ones
= 3 ones
Step 2: Subtract the tens.

7 tens − 3 tens
= 4 tens
Step 3: Subtract the hundreds.

8 hundreds − 8 hundreds
= 0 hundreds
Step 4: Subtract the thousands.

3 thousands − 2 thousands
= 1 thousand
So, we get:
The difference between the number of fishes in the two fish tanks is 1043.

2. Jason has 4147 cards. Jordan has 2237 cards. How many more cards has Jason than Jordan?

Step 1: Subtract the ones.

7 ones − 7 ones
= 0 ones
Step 2: Subtract the tens.

4 tens − 3 tens
= 1 ten
Step 3a: Regroup.
2 hundreds cannot be subtracted from 1 hundred, so we regroup the thousands and the hundreds.

4 thousands 1 hundred
= 3 thousands 11 hundreds
Step 3b: Subtract the hundreds.

11 hundreds − 2 hundreds
= 9 hundreds
Step 4: Subtract the thousands.

3 thousands − 2 thousands
= 1 thousand
So, we get:
Jason has 1910 more cards than Jordan.

3. Susan and Anna had 3131 clips altogether. Susan had 1465 clips. Find the number of clips that Anna had.

Step 1a: Regroup the tens and the ones.

5 ones cannot be subtracted from 1 one, so we regroup the tens and the ones.

3 tens 1 one
= 2 tens 11 ones
Step 1b: Now, subtract the ones.

11 ones − 5 ones
= 6 ones
Step 2a: Regroup the hundreds and the tens.

6 tens cannot be subtracted from 2 tens, so we regroup the hundreds and the tens.

1 hundred 2 tens
= 0 hundreds 12 tens
Step 2b: Now, subtract the tens.

12 tens − 6 tens
= 6 tens
Step 3a: Regroup the thousands and the hundreds.

4 hundreds cannot be subtracted from 0 hundreds, so we regroup the thousands and the hundreds.

3 thousands 0 hundreds
= 2 thousands 10 hundreds
Step 3b: Now, subtract the hundreds.

10 hundreds − 4 hundreds
= 6 hundreds
Step 4: Subtract the thousands.

2 thousands − 1 thousand
= 1 thousand
So, we get:
Anna has 1666 clips.

4. Mrs. Joseph earned \$4000. She spent \$2876 and saved the rest. How much money did she save?

Step 1a: Regroup the thousands and hundreds.
Since the ones, tens and hundreds are all zeroes, we start by regrouping the thousands.

3 tens 1 one
= 2 tens 11 ones
Step 1b: Regroup the hundreds and tens.
Since the ones, tens and hundreds are all zeroes, we start by regrouping the thousands.

10 hundreds
= 9 hundreds 10 tens
Step 1c: Regroup the tens and ones.

10 tens
= 9 tens 10 ones
Step 1d: Now, subtract the ones.

10 ones − 6 ones
= 4 ones
Step 2: Next, subtract the tens.

9 tens − 7 tens
= 2 tens
Step 3: Then, subtract the hundreds.

9 hundreds − 8 hundreds
= 1 hundred
Step 4: Lastly, subtract the thousands.

3 thousands − 2 thousands
= 1 thousand
So, we get:
She saved \$1124.

5. Mr. Yap had 1354 mangoes. He sold 893 mangoes. How many mangoes had he left?
