2. You can regroup to trade 10 ones for 1 ten.
3. 20 ones are the same as 2 tens.

Explanation:
Go-Math-Grade-2-Answer-Key-Chapter-5-2-Digit-Subtraction-11

1.  A digit is a single symbol that is used to make numerals, so the digits can be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 are the ten digits which we will use every day.
2. Here, regrouping is defined as the process of making and then carrying out the operation like addition with two-digit numbers or larger than the two-digit numbers. And we use regrouping in addition when the sum of two digits in the place value column is greater than nine. And Regrouping in subtraction is a method of interchanging one ten into ten ones. This regrouping of subtraction is used to work out the different subtraction problems. We can regroup to trade 10 ones for 1 ten. And we can regroup to trade 10 ones for 1 ten.
3. 20 ones are the same as 2 tens. As two tens mean 2 × 10= 20 and 20 × 1= 20, so 20 ones are the same as 2 tens.

Question 1.
Greg has 60 building blocks. His sister gives him 17 more blocks. He uses 38 blocks to make a tower. How many blocks are not used in the tower?
2nd Grade Go Math Answer Key Chapter 5 2-Digit Subtraction 239
__ blocks

Answer:
The number of many blocks are not used in the tower is 5 blocks.

Explanation:
As Greg has 60 building blocks and his sister gives him 17 more blocks, so the number of blocks did Greg had now is 60 – 17= 43 blocks and he uses 38 blocks to make a tower so the number of many blocks are not used in the tower is 43 – 38= 5 blocks. So we will perform regrouping of subtraction. Here Regrouping in subtraction is a process of exchanging one ten into ten ones. We use regrouping in subtraction when the minuend is smaller than the subtrahend. So the number of many blocks are not used in the tower is 5 blocks.

Sara has 18 crayons. Max has 19 crayons. How many more crayons do they need to have 50 crayons altogether?
__ crayons

Answer:
They need 13 crayons more do they need to have 50 crayons altogether.

Explanation:
As Sara has 18 crayons and Max has 19 crayons, so the total number of crayons do they have together is 18 + 19= 37 crayons. So to get 50 crayons altogether we need to perform subtraction. So we need 50 – 37= 13 crayons more do they need to have 50 crayons altogether. So we will perform regrouping of subtraction. Here Regrouping in subtraction is a process of exchanging one ten into ten ones. We use regrouping in subtraction when the minuend is smaller than the subtrahend. So They need 13 crayons more do they need to have 50 crayons altogether.

Question 2.
Jon has 12 pennies. Lucy has 17 pennies. How many more pennies do they need to have 75 pennies altogether?
__ pennies

Answer:
They need 46 pennies more to have 75 pennies altogether.

Explanation:
As Jon has 12 pennies and Lucy has 17 pennies, so the total number of pennies together they have is 29 pennies. So to 75 pennies together we need to perform subtraction 75 – 29= 46 pennies. So the number of many frames does he still have now is 32 – 15= 17 frames. So we will perform regrouping of subtraction. Here Regrouping in subtraction is a process of exchanging one ten into ten ones. We use regrouping in subtraction when the minuend is smaller than the subtrahend. So the total number of pennies together they have is 29 pennies. So to 75 pennies together we need to perform subtraction 75 – 29= 46 pennies.
