To determine the factor pairs for the number 30, simply find out the smallest set of numbers that will multiply to give 30, you would need to break down composite numbers to do this.
30 = 6 • 5 = 2 • 3 • 5.
These all are prime numbers that when multiplied together equals 30.
(11 + 21) - ( 3 - 100 )
= 32 + 97
= 129
or (11+21)-(3+100)
= 32 - 103
= - 71
