[Grade 9 math] I don’t understand this question.

[u/Long_Rough6073]

Am I supposed to be trying to get the highest possible answer with 7’s or am I trying to use combinations of 7 to equal the number on the left?

[u/Accio_149209]

Is this question a fucking 67 joke?

[u/Long_Rough6073 → u/Accio_149209]

Idk honestly.

[u/testtdk → u/Accio_149209]

Are 67 fans in 10th grade yet? I thought they were closer to ten and under, but I’m sure I’m wrong. (And even if they’re not, there’s nothing saying that the teacher/creator are getting it wrong).

[u/Guiitens2005]

Considering the exemple it looks like you have to either add or subtract, probably from lowest to highest, only using the number 7 six times 7-77777, 77-7777, 777-777, and so on Why would a question be: 1. Worded like this? 2. And a 67 joke?

[u/Unable_Pumpkin987]

They want you to make an equation that uses exactly six 7s, and any combination of signs, to produce each number from 0 to 15 (if you can).

The first example is 777-777=0.

Another example might be something like 77/77 + 7/7 = 2.

In each box, you’re trying to make an equation that equals the number on the left of the box.

See if you can figure out how to make 1, or 3.

Yes that’s what me and my friend though, but why would it be worded “how high can you count?”

[u/casce → u/Long_Rough6073]

Because you start with 0 and go up. It wants you do do them in order.

0 = 777 - 777

1 = 7 / 7 * 7 / 7 * 7 / 7

2 = 77 / 77 + 7 / 7

3 = 7 / 7 + 7 / 7 + 7 / 7

4 = ...

5 = ...

6 = ...

It wants to see how high you can go. It's actually kind of fun.

[u/Long_Rough6073 → u/casce]

Ahhh ok thanks.

[u/Accio_149209 → u/casce]

If it really wants this then this is some weird ass question.

[u/gt201 → u/Accio_149209]

I’ve done 4 4s as a community builder first day of math classes. Students work in groups though and then we do Scattegories rules that if your group as an expression that no other group had you get a point.

[u/setibeings → u/casce]

I don't think you're supposed to just give them a freaking answer sheet.

[u/casce → u/setibeings]

I did the easy ones. They'll get harder but you're right, maybe I should have stopped at 3

[u/bunchout → u/Long_Rough6073]

Because it is numbers 1-15 in order. So you are “counting” to 15 by using six sevens.

[u/ugurcansayan → u/Long_Rough6073]

Using six 7s…

Can you count to 3? To 5? 10?

How high can you count?

[u/FlammableFishy → u/Long_Rough6073]

Because counting is naming numbers in sequential order. When I count, I say 1, 2, 3, 4, 5, 6 etc.

This is what you are doing: use only 7s to “count” and see how high you can go. So far, you haven’t counted at all.

0 = 777 - 777
1 = 777/777
2 = 7/7 + 7/7 + 7 - 7

I have counted to two using only 7s. Now you do the next 12.

[u/Top_Bluejay_5323 → u/Long_Rough6073]

To see how high you can get without skipping numbers. Maybe you can get more than 1-15

[u/McCrystalKittys]

Yes what multiplication, division, subtraction etc gets big numbers

[u/Long_Rough6073 → u/McCrystalKittys]

So I just try to get the biggest possible number? Factorials square roots etc?

[u/McCrystalKittys → u/Long_Rough6073]

Yes but have to use exactly 6….7’s

🫴🫴

[u/Long_Rough6073 → u/McCrystalKittys]

😂

[u/cschotts]

im in college and i dont either

[u/testtdk]

I hate the seemingly increasing trend of math teachers giving worksheets from awful workbooks. This is among the dumbest math assignments I’ve ever seen.

[u/Nfarrah]

4 = 77 / 7 - 7 + 7 - 7
5 = 77 / 7 - 7 + 7/7
