Question

What combinations would work?

Answer 1

The answers are given below.

Explanation:

1. 4 ------ 4 ------ 4 ------ 4 = 1

⇒ (4 ÷ 4) × (4 ÷ 4) = 1

⇒
`$ \bigg( (4)/(4) \bigg ) * \bigg( (4)/(4) \bigg) $` = 1

2. 4 ----- 4 ------ 4 ------ = 2

⇒ (4 × 4) ÷ (4 + 4) = 2

⇒
`$ (4 * 4)/(4 + 4) = (16)/(8) $` = 2

3. 4 ------ 4 ----- 4 ----- 4 = 3

⇒ (4 + 4 + 4) ÷ 4 = 3

⇒
`$ (4 + 4 + 4)/(4) = (12)/(4) = 3 $`

4. 4 ----- 4 ----- 4 ----- 4 = 4

⇒ ((4 - 4) ÷ 4) + 4 = 4

⇒
`$ (0)/(4) + 4 = 0 + 4 = 4 $`

5. 4 ----- 4 ------ 4 ----- 4 = 5

⇒ ((4 × 4) + 4) ÷ 4) = 5

⇒
`$ (16 + 4)/(4) = (20)/(4) = 5 $`

6. 4 ----- 4 ----- 4 ------ 4 = 6

⇒ (4 + 4) ÷ 4 + 4 = 6

⇒
`$ (8)/(4) + 4 = 2 + 4 = 6 $`

7. 4 ----- 4 ----- 4 ----- 4 = 7

⇒ 4 - (1 - 4) = 7

⇒
`$ 4 - 1 + 4 = 8 - 1 = 7 $`
