Answer 1

your answer is

3+6= 1189

is it correct ?

I applied
3+6
3*6
then 1 at the first

Answer 2

In this term 3+6=450.75

proof:
We are given 2+3=165
3=165/2
3=82.5................(1)

Then,
We know that 5+1=6

we are given 5+4=1227
5=1227/4
5=306.75

Again,
1+2=123
1=123/2
1=61.5

5. +1. =6
306.75+61.5=368.25................(2)

On adding equation 1 and 2

82.5+368.25=450.75

Then 3+6=450.75
