[Olderisbetter]

Others are saying 35

 

[mechman]

80 or a fruit salad.

 

[tom2207]

the last + isnt a +

 

[Spark plug]

Banana = 15
1 x cherry = 5
Apple = 4

(15+5)x4=80

 

[Mr Fro]

55

Edit, didn't notice the single cherry... 35.

 

[Olderisbetter]

Calculator says 15+5×4 is 35

 

[eLuSiVeMiTe]

80


Edit. Read the X as a + first time.

 

[wyn]

35

the multiplication is done before the addition.

 

[Spark plug]

Calculator says 15+5×4 is 35

Because you haven’t pressed equals after 15 + 5, so you have worked out 5x4=20, +15=35

 

[tom2207]

theres no parenthesis either though ,, thats where the argument starts

but Bodamas Rule applies ..
I actually thought it was Bodamans Rule , but its not its Bodamas ,,,

 

[Olderisbetter]

I was looking at it as if i gave 4 people £15 and then another £5 each it would cost me £80, but not i will just give the £35 between them
