Step-by-step solution for: Simple Math | Teaching math to students with special needs
Let’s solve each addition problem one by one. We’ll add the numbers column by column — first the ones (right column), then the tens (left column). If the ones add up to 10 or more, we carry over the extra ten to the tens column.
---
Problem 1: 67 + 92
- Ones: 7 + 2 = 9
- Tens: 6 + 9 = 15 → write down 5, carry over 1? Wait — no, since it’s just two digits and we’re adding directly, 6+9=15 → so total is 159? Let’s check:
Actually, let’s do it properly:
```
67
+ 92
----
159
```
Yes: 7+2=9, 6+9=15 → so 159.
Wait — that can’t be right for a 2-digit worksheet? But 67+92 is indeed 159. The topic says “Addition (2-Digit)” but doesn’t say the answer must be 2-digit. So it’s fine.
But let me double-check all problems carefully.
Actually, looking again — maybe I misread. Let me list them all with correct calculations.
I will go step by step for each problem.
