Descibe how you would find the sum of 24,36, and 13. due tonight

2436 + 13 = 2449. you would count up 13 from 2436, or using the way I do it, since there are to digits in 13, and the 1 is in the second digit, add 1 to the second digit of 2436, so the 3. this makes 4 in that place. then all you have left is to add 3 to 6, making 9. so you are left with 2449. Plz plz plz give me brainiest answer I only need 4 more to rank up. If u do I will show my work.
