Purpose
Regroup an addition without changing its value.
Complete fictional source

One own invitation
Try 258 + 167. Show the regroup or describe it exactly.
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.
