Addition — Putting Together

🍎🍎 + 🍎🍎🍎 = 🍎🍎🍎🍎🍎    →   2 + 3 = 5

NUMBER LINE: Jump forward to add!
  2 + 3 = ?
  0──1──2──3──4──5──6──7──8──9──10
              ↑  →→→→→↑
          start 2  +3  = 5

Addition Table (1-5):
  +  │ 1  2  3  4  5
  ───┼──────────────
  1  │ 2  3  4  5  6
  2  │ 3  4  5  6  7
  3  │ 4  5  6  7  8
  4  │ 5  6  7  8  9
  5  │ 6  7  8  9  10

Subtraction — Taking Away

🍎🍎🍎🍎🍎 − 🍎🍎 = 🍎🍎🍎    →   5 − 2 = 3

NUMBER LINE: Jump backward to subtract!
  5 − 2 = ?
  0──1──2──3──4──5──6
              ↑←←←←↑
           land=3  start=5, go back 2

TRICK: If 3 + 4 = 7, then 7 − 4 = 3 and 7 − 3 = 4
