The sum of a single number is the number itself. But usually the word "sum" is used for adding more than just one number.
The total sum is: 25+52+10 = 87
Find the sum is just another way of expressing add 25 and 83. 25+83=108
10+25=35
25 + 8 = 33
It is: 43+25 = 68
The sum of the first 25 prime numbers is 1,060.
The sum of the first 25 numbers is 25*26/2 = 325 So the sum of the first 25 multiples of 12 is 325*12 = 3900
The sum is 14913.
The sum of the first 25 prime numbers is 1,060.
The total sum is: 25+52+10 = 87
Sum of 1,2, ... , n is n*(n+1)/2 Here, n = 25 so sum = 25*26/2 = 325
100 + 25 = 125
10+25=35
25 + 8 = 33
It is: 43+25 = 68
1118 + 25 = 1143 !
