Answer 1

pretty obvious

2 4 4 + 4 2 = 2 8 6

17

also obvious.

There are only a few possibilities for each of these. Did you even try?

Answer 2

between the 2nd and 3rd 4 and

2. 17.

Billruss is right, did you even try?  There are only 11 choices for 2 and you're only adding 2 digits, so unless you're about 5 yrs old, it's a pretty easy solve.  If you don't learn now, everything that comes afterwards is just going to be harder and harder.  Math builds on previous knowledge.

Answer 3

1. 244 + 42 = 286

2. If it is a number between 10 and 20, then you know that its first digit is 1. You also know that the sum of the two digits is 8. So what plus 1 equals 8? 7!  So your number is 17.

Answer 4

244+42=286

for the second part, ans. is 17
