you don't, 5-2=3 not 4
You take the F,& E from FIVE = Roman numeral IV =4
-4
You take 4 times 5 which is 20 then 3 plus 2 which is 5. Add 20 plus 5 and you get 25. That's the answer.
2 ÷ 4/5 = 5/2 or 21/2
5!=5*4*3*2*1
it would take 8 2's and 5 4's to build it.
-4
it can take 2-5 minutes to hatch
-4
Let the 5 digits nos be abcdef Without Repetition , a can take values from (1-5) -5 b can take only 4 values since no repetition c can take only 3 values d can take only 2 values e can take only 1 values Total = 5*4*3*2*1=120 With Repetittion a can take values from (1-5) -5 b can take 5 values since no repetition c can take 5 values d can take 5 values e can take 5 values Total = 5*5*5*5*5=3125
2-4, 3-2, 4-5, 4-4, 5-5

About 2-4 hours
It is {1, 2, 2, 4, 4, 4, 4, 5, 5, 5, 5, 5, 9, 12}
There are 64 subsets, and they are:{}, {A}, {1}, {2}, {3}, {4}, {5}, {A,1}, {A,2}, {A,3}, {A,4}, {A,5}, {1,2}, {1,3}, {1,4}, {1,5}, {2,3}, {2,4}, {2,5}, {3,4}, {3, 5}, {4,5}, {A, 1, 2}, {A, 1, 3}, {A, 1, 4}, {A, 1, 5}, {A, 2, 3}, {A, 2, 4}, {A, 2, 5}, {A, 3, 4}, {A, 3, 5}, {A, 4, 5}, {1, 2, 3}, {1, 2, 4}, {1, 2, 5}, {1, 3, 4}, {1, 3, 5}, {1, 4, 5}, {2, 3, 4}, {2, 3, 5}, {2, 4, 5}, {3, 4, 5}, {A, 1, 2, 3}, {A, 1, 2, 4}, {A, 1, 2, 5}, {A, 1, 3, 4}, {A, 1, 3, 5}, {A, 1, 4, 5}, {A, 2, 3, 4}, {A, 2, 3, 5}, {A, 2, 4, 5}, {A, 3, 4, 5}, {1, 2, 3, 4}, {1, 2, 3, 5}, {1, 2, 4, 5}, {1, 3, 4, 5}, {2, 3, 4, 5}, {A, 1, 2, 3, 4}, {A, 1, 2, 3, 5}, {A, 1, 2, 4, 5}, {A, 1, 3, 4, 5}, {A, 2, 3, 4, 5}, {1, 2, 3, 4, 5} {A, 1, 2, 3,,4, 5} .
