Four fives do not equal 18 - they equal 20.
They are worth 8.
(.5x5)x5+.5=13
55 + 5/5 = 56
Examples of sums using four fives to get 80:55+5×55!!×5+√(5×5)(55-5!!)/.5(5×5-5!!)/.55!-5×5-5!!((5!!/5)!)!/5×.(5)

Four fives
Times. Four of fives is four lots of fives of 4 times five which is 20.
Do you mean four fifth's? If so,there are two fives in ten and so, if heading wfor i decimal place, half the nominator (in this case four) which equals two so the answer will most likely to be 0.2.Hope it helped you . x :)EDIT: 4/5 as a decimal is 0.8 !
