Percent literally means 'of one hundred' and 100% of 100 is 100, so 1% of 100 is 1
1 + 10000 + 8500000 = 8510001
1 +100 = 101 100 - 1 = 99 99 +1 = 100 100 times 100 =10000 10000 divide by 2 = 5050Ans:5050
Using a pen or a keyboard
1+2+3+4+5=15 15+10000=10015 One would think it would not be hard to punch these into a calculator.
1000 plus 10000 equals 11000
42003 + 10000 = 52003
40000 + 10000 = 50000
25 + 10000 = 10025.
5000 + 8250 + 100 + 1000 + 6500 + 1000 + 6500 + 1500 + 1500 + 10000 + 1000 + 10000 + 100 + 8250 + 5000 + 5000 + 8250 = 78,950
