How is (1+3)**2=16 ??

Answer 1

first 1+3=4 then 4^2=16

Answer 2

In Python '**' operator is power operator, so:

( 1 + 3 ) to power of 2 == 16 ;)

Answer 3

It is 16.0, not 16!

Answer 4

@Ali Emir Kizil:

'=16' was to be read in human language, where '16==16.0'

... else it's neither '16' nor '16.0' at output, it's a syntax error :P

Brackets come first (1+3)=4
4**2
** means square or multiple 4 two times
4x4=16
