The zero point is the entrance, the positive direction is to the right, and the unit is metres. What signed integer displacement from zero is represented by position 4?
G001 — The zero point is the entrance, the positive direction is to the right, and the unit is metres. What signed integer displacement from zero is represented by position 4?
Definition and scope
Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Keep EACH bank’s keys/operation/domain distinct:LDL/PULSE/function legacy table underscores,TREE full tree_* with its declared domain,and permissive BASE signed without invented op/domain.All arithmetic respects the binary-primitive contract.
The zero point,positive direction,unit and position value are GIVEN in G001.Zero is at the origin;positive is along the declared direction,negative opposite,and abs(value)is magnitude.The25 ACTUAL bilingual frames were checked;do not invent a measurement or unit conversion.
Signed ORIGINAL sign times displacement magnitude := mul(1, 4)
After
Signed ORIGINAL sign times displacement magnitude = 4
Conditions: none
Use ORIGINAL operands exactly;mul/sub/div have EXPLICITLY TWO operands so the old binary primitive cannot ignore a third.Keep RAW SAFE bounds separate from unbounded derived BigInts;do not approximate to force answers.
Reconstruct the ORIGINAL signed displacement as sign*magnitude.Do not replace a negative displacement by a positive distance or reciprocal.The position is GIVEN,not guessed from a metadata flag.
