 So first I added the tens and then I got 80, then I added the ones and I got 21 and then I added those two numbers together and I got 101. First I broke the numbers, then second I added the tens and then there and then 10, 20 plus 20 plus 50 equals 80. Third I did the ones, 7, 8, 6 plus 20 equals 21 and then 80 and I put 20 with the 80 and it equaled 100. Then I added one more and I made 101. Okay, I did a number line, I got 17, jumped 20, I jumped 8 and then with the 20 I got 37 and 8 which equals 45. Then I jumped 50 and then I got 50, I jumped 6 and then I ended up 101.
