Solution:
Q1: 111-11=100
Q2: [5x5x5]-5x5=100
Q3: [33x3]+3/3=100
On question No.1 you first use three ones to make 111. Then you
use the other two ones to make 11 and subtract 111 from 11 and get
100.
------------------------------------------------------------
On question No.2 you multiply 5x5x5 and get 125. then you multiply
the other two fives and get 25. then you subtract 125 from 25 and
get 100
------------------------------------------------------------
On No.3 you multiply 33x3 and get 99. then divide 3 from 3 which
equals 1. then add them together to get 100.

Solution:
Q1: 111-11=100
Q2: (5x5)x5-(5x5)=100
Q3: 3x33+3/3=100
Q1:I subtracted 11 from 111 and got 100. Q2:I multiplied 5 and 5
to get 25 and multiplied 25 to 5 in order to get 125. 125 subtracting
25(5x5) would equal 100. Q3:I multiplied 3 with 33 and got an answer
of 99. 100-99=1 In order to get 1, I used the fraction 3 out
of 3 which is 1. 99+1=100
About me: Ever since 2nd grade I liked to answer math questions
