I am not sure how to go about figuring this out ... Shuffle the numbered cards of an ordinary deck of cards (aces equal 1). Pick out one card to be the answer card. Then deal off the top four cards to use for an equation. Try to use 2,3,or all 4 cards to form an equation. Example: Answer card is 4. Equation cards are 2, 6, 8, and 10. Possible equations are(10 + 6 - 8)divided by 2 = 4 or 8 +2 - 6 =4. Assign 5 points if you use all 4 cards to make an equation, 3 points for using 3 cards, and 1 point for using only 2 cards. ..... i am stumped .... any help would be appreciated!
The idea here is to get a deck of cards and follow the instructions. I don't know what the answer card will be nor what the other four cards will be (and neither do you) so just get a deck and try it. Now if YOU CAN PICK the cards, you might get somewhere by picking an answer, then pick cards that will give you that answer. But I don't think that's the idea.
Ding dong ... the lightbulb turned on .. thank you ... got it figured out!
To solve this problem, you need to find equations using the given set of cards that yield the answer card.
Here are the steps you can follow to determine if an equation can be formed using 2, 3, or all 4 cards:
1. Shuffle the numbered cards of an ordinary deck.
2. Pick one card as the answer card.
3. Deal off the top four cards to use for the equation.
Now, let's consider the possible scenarios:
1. Using 2 cards:
Take the two equation cards and try to form an equation with them that results in the value of the answer card. For example, if the answer card is 4 and the equation cards are 2 and 6, you can subtract 2 from 6, which equals 4: 6 - 2 = 4.
2. Using 3 cards:
Take three of the equation cards and try to form an equation that results in the value of the answer card. If the answer card is 4 and the equation cards are 2, 6, and 8, you can add 2, 6, and 8 together and then subtract the sum from the answer card: 2 + 6 + 8 - 4 = 12 - 4 = 8. This equation uses 3 cards.
3. Using all 4 cards:
Take all four equation cards and try to form an equation that results in the value of the answer card. If the answer card is 4 and the equation cards are 2, 6, 8, and 10, you can subtract 8 from 10, then add that result to 2, and finally divide the sum by 2: (10 - 8 + 2) / 2 = 4. This equation uses all 4 cards.
Remember to check all possible combinations of the equation cards for each scenario. If you find any equations that meet the criteria, assign the corresponding points:
- 5 points for using all 4 cards.
- 3 points for using 3 cards.
- 1 point for using 2 cards.
I hope this explanation helps you understand how to approach this problem and find the possible equations.
