4 when you plus 8 the answer will 12, 12 when you minus 8 the answer will 47 when you plus 8 the answer will 15, 15 when you minus 8 the answer will 7
Just like a triangle when you minus or plus something the answer will be inside of the triangle.
We had the following solution from pupils in the Philippines:
Students of Olongapo City National High School, Philippines. Leader: Jumer Palacio
Members:Joachim, Lee Anthony, Meynard, Kimberly, Erwin, Arlan, Von Nairo
The first time, 10 was put in a box and the result when it came out is 18.?? 10 ? 18 = -8
-8 is the difference of the two number before and after it was put in the box.
We wonder if where we able use this number to our next line of numbers that have been put in the box.
The next line-up is 12, 8, 15. We minus -8 from the line of numbers written before this sentence.
12 - 8 = 4 8 - 8 = 0 15 - 8 = 7
We thought of similarities between the given answers and we come up of this solution:
4 when you plus 8 the answer will 12, 12 when you minus 8 the answer will 4
7 when you plus 8 the answer will 15, 15 when you minus 8 the answer will 7
Just like a triangle when you minus or plus something the answer will be inside of the triangle.
The next line up of numbers are: 0, 19, 1, 11. First, we need to find out on which number 10 will be added on one of the number on the line.We put the 10 on 0 so it becomes 10.
The new line-up is 10,19, 1, 11. There is a new add and subtract of number on this line-up, the number 8.
We thought of what is the similarities to each other and we come up to this solution: 10+19+1+11=41 2+27-7+3+19=41
For the answer -8 for plusing and minusing for the numbers inside the box.THAT?S WHAT HAPPENED IN THE BOX!
We also had the following from Carly in Ashington:
The first numbers were adding 8,6,10,3
The second numbers were subtracting and adding 10,9,9,1
Thank you for these solutions.
Alfie from Hunters Bar Infant School sent in a good very late solution.
