1345:3-45

I’m not sure how to read "1345:3-45." Could you clarify the intended operation? Here are the two most common readings, with results: - If ":" means division and the expression is 1345/3 − 45: - 1345/3 − 45 = (1345 − 135)/3 = 1210/3 ≈ 403.3333 - Exact form: 1210/3 - If ":" means division and the expression is 1345/(3 − 45): - 3 − 45 = −42, so 1345/−42 = −1345/42 ≈ −32.0238 - Exact form: −1345/42 If you meant something else (for example a ratio 1345:3−45 or a different grouping), please tell me the precise parentheses or operators, and I’ll compute it.
