• reckon 本词

  In this sense, somewhat old-fashioned or formal/dialectal, as in reckoning up a sum by hand; its far more common modern use means to think or guess, not calculate.

  在“计算”这一意义上略显过时或带有方言或书面语色彩，如手工“合计”一笔账；它在现代更常见的用法是“认为、猜想”，而不是计算。

All four can mean to work out a number. Calculate is the neutral, most common word. Figure is informal, suggesting a quick, mental calculation. Compute is formal, often for machine calculations. Reckon here is old-fashioned; it often means to think or guess.

这四个词在“用数字或方法计算出结果”这一意义上相近，但语域和使用习惯不同：calculate是最常用、最中性的说法；figure更口语化，常见于非正式场合；compute偏正式，常用于数学、科学或计算机系统的运算；reckon在“计算”这一意义上略显过时或带有书面或方言语气，而且它更常见的用法是表示“认为、猜想”，这里不比较reckon表示“认为”的意思。

比较义项：认为，猜想（动词）。

Think, suppose, and reckon all mean to believe or guess, but differ in certainty and formality. Think is the most common, neutral verb for any opinion. Suppose suggests a tentative guess, and often softens a statement. Reckon is informal, mainly British or Australian speech.

这三个词都可以表示“认为、猜想”，但确定程度和正式程度不同：think 最常用、最中性；suppose 强调基于可能性的推测，语气较不确定，也常用来委婉缓和语气；reckon 是非正式口语，多见于英式／澳式英语，正式场合不用。这里不比较 suppose 的“应该”义（be supposed to）和 reckon with 的“应对，处理”义。
