Adding means putting groups together to find how many there are in all. We write it with the plus sign, +. The answer comes after the equals sign, =.
You can count on from the bigger number. For 2 + 6, start at 6 and count on two more: 7, 8. You can add numbers in any order and get the same answer.
Some facts are worth knowing by heart, like 5 + 5 = 10 and 4 + 4 = 8. Adding 0 changes nothing: 7 + 0 = 7.
