Well, honey, 100 plus 1000 equals 1100. It's basic math, darling. Keep those numbers in line and you'll be just fine.
800
200 + 200 + 200 + 200 + 200 = 1000
200 plus 79 equals 279
200
How about: 800+200 = 1000 or 2*500 = 1000
2000
1/5 of 1000 equals 200
1000 plus 10000 equals 11000
20% of 1000 is 200 therefore: 1000 + 200 = 1200
6000.......it's actually 5,100
100 100 004 001 ------- 205 -------
