ACTIVITY 3: The Message Mender | HINTS ONLY

Read one hint at a time. Pause, skip or reveal the answer whenever you want.

HINT 1
The four number positions are read from left to right. Try deciding which one position changed; the other three must stay exactly as printed.

HINT 2
Check both addition rules. If first + second = third already works but second + third = fourth fails, only the fourth number can change. If only the second rule already works, only the first number can change.

HINT 3
For strip 1, try keeping its printed first two numbers, 3 and 2. Their sum fixes the third number. Adding the second number to that result fixes the fourth. Does this repair change exactly one number?

HINT 4
After repairing strip 1, use chart row 3 and column 2 for its letter. Repair and decode the remaining strips the same way. Use the printed letter order and word breaks; a wedding-themed guess is unnecessary.
