can u help me by splitting them its to hard!
1.87-8=
2.53-5=
3.92-5=
4.65-8=
5.23-5=
6.84-8=
7.91-9=
A few:
1) 87-8 =88-8+1
5) 23-5= 20-5+3
7) 91-9=90-9+1

7) 91-9=90-9+1
Sure! I can help you split them.
To solve these equations, you can use the method of regrouping or borrowing. Here's how you can do it step by step:
1) 87 - 8:
Start from the rightmost digit (7). Can 8 be subtracted from 7? No. So, borrow 1 from the tens place, making it 7-1=6 in the tens place. Now, you have 17 in the ones place. Can 8 be subtracted from 17? Yes, it can. So, subtract 8 from 17 to get 9. The answer is 79.
2) 53 - 5:
Start from the rightmost digit (3). Can 5 be subtracted from 3? No. So, borrow 1 from the tens place, making it 4-1=3 in the tens place. Now, you have 13 in the ones place. Can 5 be subtracted from 13? Yes, it can. So, subtract 5 from 13 to get 8. The answer is 48.
3) 92 - 5:
Start from the rightmost digit (2). Can 5 be subtracted from 2? No. So, borrow 1 from the tens place, making it 9-1=8 in the tens place. Now, you have 12 in the ones place. Can 5 be subtracted from 12? Yes, it can. So, subtract 5 from 12 to get 7. The answer is 87.
4) 65 - 8:
Start from the rightmost digit (5). Can 8 be subtracted from 5? No. So, borrow 1 from the tens place, making it 5-1=4 in the tens place. Now, you have 15 in the ones place. Can 8 be subtracted from 15? Yes, it can. So, subtract 8 from 15 to get 7. The answer is 57.
5) 23 - 5:
Start from the rightmost digit (3). Can 5 be subtracted from 3? No. So, borrow 1 from the tens place, making it 2-1=1 in the tens place. Now, you have 13 in the ones place. Can 5 be subtracted from 13? Yes, it can. So, subtract 5 from 13 to get 8. The answer is 18.
6) 84 - 8:
Start from the rightmost digit (4). Can 8 be subtracted from 4? No. So, borrow 1 from the tens place, making it 8-1=7 in the tens place. Now, you have 14 in the ones place. Can 8 be subtracted from 14? Yes, it can. So, subtract 8 from 14 to get 6. The answer is 76.
7) 91 - 9:
Start from the rightmost digit (1). Can 9 be subtracted from 1? No. So, borrow 1 from the tens place, making it 9-1=8 in the tens place. Now, you have 11 in the ones place. Can 9 be subtracted from 11? Yes, it can. So, subtract 9 from 11 to get 2. The answer is 82.
I hope this helps! Let me know if you have any more questions.
