Question

evaluate python expression 3+4//7-8*(2**2)

Answer 1

use precedence rule here:

(**) has highest precedence in all operator.

3 + 4 // 7 - 8*(2**2) = 3 + 4 // 7 - 8*(4)

or, 3 + 4 // 7 - 8*4 = 3 + 0 - 8*4

(//, & * has same precedence hence evaluation on the basis of L --> R)

or, 3 + 0 - 32 = - 29

Answer 2

Answer:

-29

Explanation:

The priorities of operators in python are as followed:

• ()
• ^ or * *
• /, // , %, *
• +,-

Using that,

we solve it in the following order:

• 3+4//7-8*(2* *2)

• 3+4//7-8*4
• 3+0-32
• -29
