Sums - Series of Integers 1 to N - Text to Addition (Level 1)

This math topic focuses on practicing the creation of addition equations representing the sum of consecutive integers from 1 to a given number \( N \). Each question presents students with a range of integers and asks them to formulate the correct sequential addition expression that totals the inclusive sum from 1 up to \( N \). The topic helps students understand and work with integer sequences and basic summation concepts, reinforcing their skills in identifying patterns in number sequences.
