Complete source
An invented card kit needs 725 cards in total. It already has 468. How many more are needed? 468 + □ = 725.
Instruction
Choose one ordinary route or your own complete stated problem. Use any of these four empty areas. A label does not require a filled box. Adult models/answers stay on staff work.
Eligibility
Ordinary taught practice only. Held first sources and their four genuine blank prompts are separate.
Access
Show, draw, type, sign, use your usual communication or direct an agreeing helper. Choose quiet/private work, switch a route, pause, pass or finish. One useful part is enough. A helper can read the exact words or scribe your choices; supplying an operation, count, regrouping or reason is mathematical help and is named. No speed, neatness, speech, handling or device requirement.
