What does zeroed mean?
“Zeroed” is chiefly the past tense and past participle of “zero.” In its basic sense, it means that a value, balance, counter, or other reading has been set to zero: a technician may zero a scale before using it, and after calibration the display is zeroed. It can also mean reduced to nothing or eliminated, as when credits zero out a debt or cancellation fees zero the total. In technical contexts, a weapon or instrument may be zeroed by adjusting it to a correct reference point. The expression “zeroed in on” means focused intently on a person, issue, or target. These uses are common in standard English, although some extended senses sound informal or jargon-like. The word is useful because it expresses both a precise mathematical operation and, figuratively, the cancellation or elimination of something. Its familiar uses appear in finance, technology, engineering, military terminology, and everyday discussion.
To set a value or reading to zero; reduce or eliminate something; adjust an instrument to a zero reference point; or focus closely on a target.

The focus and destruction senses are commonly expressed through the established phrasal forms “zeroed in on” and “zeroed out.”
Having been set to zero or adjusted to a correct zero reference point.

This use is especially common in technical, engineering, and military contexts.
Zero was a late arrival in mathematics—and the blank it represented eventually changed calculation forever.

Etymology of zeroed
Zeroed is formed from zero with the English suffix -ed, marking a past tense and past participle. The word zero entered English through French zéro and Italian zero and is ultimately connected with Arabic sifr, meaning “empty” or “cipher,” from Sanskrit śūnya, meaning “void” or “emptiness.” The development of the numeral itself was part of the wider adoption of Hindu-Arabic place-value reckoning in European mathematics.
