It is the sum of the integers from 1-41 minus the sum of the integers from 1-24 divided by 17
the sum of the integers from 1-41 is (42)(45)/2 = 861
the sum of the integers from 1-24 is (24)(25)/2 = 300
(861-300)/17 = 33
The answer is 33
1.a)add
B) substract
C) multiply
D) one
2) 1002=1.002×10^3
3)2.8×10^-3 < 2.5×10^-2 < 1.2×103 <4×103
