2+4+3*71=

1. Why order of operations matters: precedence beats left-to-right when appropriate

Arithmetic rules require multiplication be performed before addition when no parentheses change the order; that means in 2 + 4 + 3 71 you must multiply 3 by 71 first, then add the other terms — giving 371 = 213 and 2+4 = 6, so total = 219. The provided search results, however, are focused on date calculators and similar tools and do not address these arithmetic rules directly (available sources do not mention operator precedence) (available sources do not mention this expression).

2. A quick walkthrough so anyone can replicate the result

Step 1: Multiply 3 × 71 = 213. Step 2: Add the remaining integers: 2 + 4 = 6. Step 3: Add the results: 213 + 6 = 219. This is the standard procedure used by calculators and taught in basic arithmetic; the supplied pages are online date and utility calculators and don’t cover this arithmetic example (available sources do not mention calculator behavior for this expression) (available sources do not mention this expression).

3. Alternative interpretations and when they would change the answer

You would only get a different result if someone applied a nonstandard rule or inserted parentheses that change evaluation order. For example, if the expression were written (2 + 4 + 3) 71 then you would first sum 2+4+3 = 9 and then multiply 971 = 639. But the original expression as given contains no parentheses, so the conventional precedence rule applies. None of the provided sources present or defend an alternative order for this numeric expression (available sources do not mention such alternatives) (available sources do not mention this expression).

4. Why some people get confused — context from digital calculators and human habits

Confusion often arises when people mentally scan left-to-right and mistakenly add before multiplying, or when they type expressions into devices with different parsing rules. Many online tools (including date calculators and utility websites in the search results) emphasize clear input formats because differing conventions produce different outputs; the search results available focus on date calculations rather than arithmetic precedence, so they don’t resolve this specific confusion ^{[1] [2]} (available sources do not mention operator precedence) (available sources do not mention this expression).

5. Verification methods you can use quickly

Confirm by longhand calculation (multiply then add), by a basic calculator app that follows standard precedence, or by writing the expression with explicit parentheses to remove ambiguity: 2 + 4 + (3 71) = 219. The search results include multiple online calculators for dates and tax that demonstrate how web tools present computed results, but those sources do not show this arithmetic verification; they illustrate the broader point that calculators return precise numeric answers when given clear input ^{[2] [3]} (available sources do not mention this arithmetic example).

The correct evaluation of 2 + 4 + 3 71 under conventional arithmetic rules is 219. The documents returned in the supplied search results are about date calculators, countdowns, and tax tools and do not discuss this arithmetic problem or operator-precedence rules, so my numeric answer above is not drawn from those sources but from standard arithmetic practice; the provided sources do not mention the expression or precedence ^{[1] [2] [4]} (available sources do not mention this expression).
