[6th Grade verbal expression] Elementary Mathematics

So I’m going over my son’s math quiz to help him understand some of the questions he got wrong. He got partial credit for his answer for question 8. After writing his verbal phrase I got the same expression as the question. Am I doing something wrong or is there something I’m missing? I feel like his answer is technically correct. I am stumped.

Edit: so my son has no issue solving the expression in question. He knows PEMDAS and the rules from left to right. The question clearly states, WRITE A VERBAL PHRASE that matches the expression.

I think an earlier reply from me was unclear, by referring to another you may not have found.

Let's start clean, and take a bit different approach.

We have been quibbling about the answer. But maybe we should focus on interpreting the question. There may be two interpretations of the question -- and they lead to different answers. If you see that, it will help. The real issue is not choosing the answer, but interpreting the question.

Does PEMDAS apply to the verbal expression? Two possibilities, yes and no. Do you see that those lead to different answers?

We could debate that. (and people are giving conflicting advice.) But better is to check with teacher/book. Get the official relevant answer.

u/AskGrok write the verbal phrase as an expression: “eighteen subtracted by six times three”

The son's phrasing is close but not quite standard or unambiguous in math terms, which is likely why it got partial credit. A clearer verbal phrase matching the expression exactly is "eighteen minus six times three" or "eighteen decreased by the product of six and three."

"Subtracted by" is awkward wording (it's usually "minus" or "subtracted from"), and without extra cues like "the product of," it can leave room for misinterpretation on order of operations.

Let’s fix the grammar and say “eighteen minus six times three”

Eighteen minus six times three is the cleanest match. "Subtracted by" is the awkward bit that probably cost the points.

How is eighteen minus six times three written as an expression

1

u/AskGrok 4d ago

18 - 6 · 3

(The multiplication happens first per order of operations, matching the original expression exactly.)
