3:17 I don't understand why it is not 8/16 but it is 16/8. in previous postfix video you took top of the stack as 2nd operand

[Tbm]

Hey i have a doubt in post fix u are dividing a number with different way. Like
Here u did 16/8
But in postfix u did 8/16. Check it

when we enter 16 then according to your previous rule here will be 8/16 this is correct but here you have done 16/8 which is wrong according to me

[manikislive]

its not 16/8 it should be 8/16 lower stack value operand upper stack value

[priyalsarda]

Sorry, but you are placing the operands with operators wrongly. it cannot be 16/8. It should have been 8/16. Check time 3:08

[fadlyahmad]

So basically the calculation same as postfix right?

[himanichoudhary]

hey guyz this explanation is wrong bcz it should be 2-4 =-2 instead of 4-2=2

[ShubhamGupta-unjf]
