Class VII Students : Maths Lab ( Addition of integers ) | Saibaba Central School | Ongole

Added: 2026-05-25

This video demonstrates integer addition using a color-coded system where orange represents positive numbers and black represents negative numbers. The examples show: adding 6 positive and 2 positive gives +8; adding 3 positive and 2 positive gives +5; adding 4 negative and 2 negative gives 6 negative; and adding 3 negative and 2 positive gives 1 negative. The core principle is that when adding integers with the same sign, the result takes that sign; when adding integers with different signs, the result takes the sign of the number with the larger absolute value.
