Directions: Using the digits 0 to 9 at most one time each, place a digit in each box so that each expression is simplified to a different odd number.
Hint
How do we know which digits are easier to place?
How can we tell which operations might affect getting a whole number result for our expression?
How can we tell which operations might affect getting a whole number result for our expression?
Answer
There are many different solutions to this problem.
5 ÷ (8 – 7) = 5
9 + 0 x 6 = 9
3 – 4 / 2 ÷ 1 = 1

Is the intent to use each number only once in the ENTIRE set?
That is my understanding Katie.
i got 9 + 0 x 6 = 9
In confused 😕
what do we do on this
hey I’m like really confused!!!
On the second set shouldn’t the answer be 54? I thought that when I was in school the math was done in order except for brackets. So the question should look like 9+(0*6)=9
I think you have to haeve an odd number and their are also many different answers for this.
HMMMMMMMMMMMMMMMMMMMMMMMMMM… Can we use decimals ¯\_(ツ)_/¯
I was forced to do this 🙁 so I feel like this rn ¯\_(ツ)_/¯
Too ez/easy
i am so confused
Can the answers be negative?
The possible solution given should end with multiplication in the equation, not division.
3 – 4 / 2 ÷ 1 = 1 should be 3 – 4 / 2 x 1 = 1
Not a big deal, just a typo.
My student and I got the following
7 / (6-5) =7
1 + 2 x 0 =1
9 – 8 / 4 x 3 =3
9 / (8-5) = 3
3 + 6 x 2 = 15 –> 3 + (6×2) = 15
7 – 4 / 1 x 0 = 7 —> 7-((4/1)x 0)) = 7
7 / ( 8 – 1 ) = 1
0 + 5 x 9 = 45
3 – 4 / 2 x 6 = 9
GOT A NEW ONE I THINK!!!
YES CORRECT
I think you have to haeve an odd number and their are also many different answers for this.
