Answer 2

The value of 230 - 220 x 0.5 is equal to 5!.

Step-by-step explanation:

We have,

230 - 220 x 0.5

To find, the value of 230 - 220 x 0.5 = ?

∴ 230 - 220 x 0.5

Using BODMAS rule,

= 230 - (220 x 0.5)

= 230 - 110

= 120

We know that,

5! = 5 × 4 × 3 × 2 × 1 = 120

= 5!

∴ The value of 230 - 220 x 0.5 = 5!

Thus, the value of 230 - 220 x 0.5 is equal to 5!.
