65 + 65 + 65 + 90 + 90 + 90 + 90 + 50 + 50 + 50 + 50 + 50 + 50 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 995
20 + 50 + 20 + 10 = 50 = 150
thinking is amazing
100 plus 50=150. 150+20=170.
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
It is so very simple and quick to get the answer if you use the calculator that comes with your computer. So why not give it a try?
18 + 10 + 20 + 30 + 15 + 50= 143
it is 113
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260
318
50 put it like this 20 plus 20 is 40 than 5 plus 5 is 10 then whats 40 plus 10 which is 50 if you dont understand that 20 plus 5 is 25
The answer to -5 plus -20 equals -25. This is taught in class.
