Let’s solve each problem step by step.
We are turning repeated addition into multiplication.
Remember:
If you add the same number over and over, you can write it as:
number × how many times you added it
Example given:
3 + 3 + 3 + 3 → that’s 4 threes → so 3 × 4 = 12
Now let’s do each one:
---
b. 4 + 4 + 4 + 4 + 4
That’s 5 fours → 4 × 5 = 20
c. 7 + 7 + 7 + 7 + 7 + 7
That’s 6 sevens → 7 × 6 = 42
d. 1 + 1 + 1 + 1
That’s 4 ones → 1 × 4 = 4
e. 2 + 2
That’s 2 twos → 2 × 2 = 4
f. 3 + 3 + 3
That’s 3 threes → 3 × 3 = 9
g. 6 + 6 + 6 + 6 + 6 + 6 + 6
That’s 7 sixes → 6 × 7 = 42
h. 5 + 5 + 5 + 5
That’s 4 fives → 5 × 4 = 20
i. 8 + 8 + 8 + 8 + 8
That’s 5 eights → 8 × 5 = 40
j. 1 + 1 + 1 + 1 + 1 + 1 + 1
That’s 7 ones → 1 × 7 = 7
---
Double-checking calculations:
- b: 4×5=20 ✔️
- c: 7×6=42 ✔️
- d: 1×4=4 ✔️
- e: 2×2=4 ✔️
- f: 3×3=9 ✔️
- g: 6×7=42 ✔️
- h: 5×4=20 ✔️
- i: 8×5=40 ✔️
- j: 1×7=7 ✔️
All correct.
Final Answer:
b. 4 × 5 = 20
c. 7 × 6 = 42
d. 1 × 4 = 4
e. 2 × 2 = 4
f. 3 × 3 = 9
g. 6 × 7 = 42
h. 5 × 4 = 20
i. 8 × 5 = 40
j. 1 × 7 = 7
