The pair of numbers are 15 and 2, or -2 and -15
15 - 2 = 13
15 x 2 = 30
-2 - (-15) = -2 + 15 = 13
(-2)(-15) = 30
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
154
half of 30 is 15, so 15 added to 15 would equal 30. if you go from there and add one number and subtract one number from each 15 (14 plus 16, 13 plus 17, ect...all the way to 0 plus 30) these numbers will also total to 30.
-17
13+17 = 30 13-17 = -4 But 17-13 = 4
30 and 1 is one possible pair.
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.

Up until 1972 Marlins serial numbers began with a letter that corresponded to a year.From 1973 on the formula changed. You take the first two number in the serial number and subtract them from 100 to get the year made. So your first two numbers are 18. Subtract 18 from 100 and you get 82. Your .30-30 was made in 1982.
