this is clearly a trick question. 20 plus 20 plus 20 is equal to 60 and there is 60 minites in 1 whole hour so 20 plus 20 plus 20 is equal to 1.
109 you can plus like this: (19+1)+20+20+(1+1+18)+4+25
No, 20 + 1 is not 20.
1 + 10 + 20 = 31
20 + 1 = 21
In fact, 1/10 + 1/10 + 1/20 + 1/4 + 1/2 is equal to 1.1/10= 2/20 1/4= 5/20 1/2= 10/202/20+2/20= 4/20+1/20=5/20+5/20=10/20+10/20=20/2020/20=1
19 + 1 = 20
-1+20 = 19
The sum of 20 added to itself 20 times is calculated by multiplying 20 by 20, resulting in 400. Therefore, the answer to the given equation is 400.
