Users were divided between the answers 20 84在两者之间来回走动。
有些用户甚至建议答案是25或320。
，但正确的答案实际上是84。
为了获得正确的答案，必须遵循PEMDA-通常在公共核心课程下以五年级或六年级教授的概念。
pemdas是一个代表括号的parter/subtrantion，从左右/乘法（左右）右）。
使用该顺序：
首先，您将20÷5除以4。
Then, you add that to 80, giving you a final answer of 84.
80 + (20 ÷ 5) = 80 + 4 = 84
Still, many users online missed the division step and just added 80 + 20 first — a common mistake if pemdas无法正确使用。
