Answer:
55
Step-by-step explanation:
The first 10 positive integers = 1,2,3,4,5,6,7,8,9,10
Their sum= 1+2+3+4+5+6+7+8+9+10
= 55
The sum of first 10 positive integers =55
( or)
The positive integers are natural numbers
so the formula can be applied for that is n(n+1)/2
here n =10
n(n+1)/2= 10(10+1)/2
= 10(11)/2
=110/2
= 55
