299
299 = -23 * -13
11m + 13 = m + 23 10m + 13 = 23 10m = 10 m = 1
(17-4)+10=23 13+10=23
13 x 23 means that, if you count 13 sets of 23 of something...or 23 sets of 13 of something, you will have 299 of that item. For example, if you have 13 rows with 23 seats in each row, you will have a total of 299 seats.

5 + n = 23 n = 18 18 - 5 = 13 ■
13 + X = 31 Or 31 - 13 = X Ergo X = 18
23-15-13-5-14
How about: 23+7 = 30 or 17+13 = 30
