You're working on a multiplication worksheet titled
“Multiplying by 0 and 1 (A)”. This is a foundational math skill where students practice multiplying numbers by 0 and 1 — two special cases in multiplication.
---
## 🧠 Key Rules to Remember:
-
Any number multiplied by 0 equals 0.
- Example: `7 × 0 = 0`, `0 × 12 = 0`
-
Any number multiplied by 1 equals itself.
- Example: `9 × 1 = 9`, `1 × 5 = 5`
These rules make this worksheet very straightforward — you don’t need to do complex calculations. Just apply the rule based on the multiplier (the bottom number).

✔ How to Solve Each Problem
Each problem looks like:
```
3
× 1
---
```
or
```
6
× 0
---
```
Step-by-step:
1. Look at the
bottom number (the multiplier).
2. If it’s
0, the answer is
0.
3. If it’s
1, the answer is the
top number.

## 📝 Let’s Solve the First Row Together
Original first row:
```
3 2 6 1 11 8 8 10 4 11
×1 ×1 ×0 ×0 ×1 ×1 ×1 ×0 ×0 ×0
```
Solutions:
- 3 × 1 =
3
- 2 × 1 =
2
- 6 × 0 =
0
- 1 × 0 =
0
- 11 × 1 =
11
- 8 × 1 =
8
- 8 × 1 =
8
- 10 × 0 =
0
- 4 × 0 =
0
- 11 × 0 =
0
✔ So the answers for the first row are:
3, 2, 0, 0, 11, 8, 8, 0, 0, 0

## 🔁 Apply This to All Rows
Since the pattern repeats, here’s how to solve the entire sheet quickly:
> For every problem:
> - If multiplier is
0 → answer =
0
> - If multiplier is
1 → answer =
top number

## 🎯 Final Tips
- Double-check that you didn’t accidentally multiply when you should have just written 0 or the top number.
- Since this is a “/100” score sheet, there are 100 problems total (10 rows × 10 problems).
- If you got all 100 correct, you earned a perfect score!
