520 = (5 x 100) + (2 x 10) + (0 x 1)
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5

The additive identity is zero. When you add a number and 0, the sum equals the original number.
0
1 plus negative 1 equals 0. If you add a negative to something, it is bassically taking it away from the adding number. In other words, you can just change the + sign to a - sign. :)
because when you add 1 to 0 it is 2
2*-2= -4 2-2= 0
0
520 can go into 7 0 times.
