Commutative property. In this a+b = b+a eg 2+5=7 & 5+2=7 so (2+5)=7=(5+2)
If you put the numbers in order it is: 0, 0, 1, 2, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 7, 7, 7, 7, 8, 9. Since there are 25 numbers, we are looking for the thirteenth number, which is 5.
7 + 6 * 5 - 2 = 7 + 30 - 2 = 35.
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
No; that is not right! 2+5=7, not 6! :)
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
2 + 5 is 7 + 6 =13 + 7 = 20 + 8 = 28 + 9 = 37 + 10 is 47.
-5 - 7 + 6 = -6
79
The answer is 39.7 + 8 = 15 + 4 = 19 + 7 = 26 + 5 = 31+ 6 = 37 + 2 =39
