First students should be taught to count numbers and make links between the numbers. Then they should learn to identify and create different representation of numbers and learn the concept of zero.
read and write numbers and to count, sort and order them. That way they can compare the size of two sets. And than students should be taught to add and subtract numbers. Adding can be learned by grouping numbers, while subtracting by moving apart given numbers.

If you would like to solve the system of equations 2x + y = -4 and y = 3x + 2, you can do this using the following steps:
<span>2x + y = -4
y = 3x + 2
</span>_________
<span>2x + y = -4
</span>2x + 3x + 2 = -4
5x = -4 - 2
5x = -6
x = -6/5
y = 3x + 2 = 3 * (<span>-6/5) + 2 = -18/5 + 10/5 = -8/5
</span>
(x, y) = (-6/5, -8/5)
The correct result would be (-6/5, -8/5).
If you would like to evaluate f - 2 * g for f = 3 and g = 27, you can do this using the following step:
f - 2 * g = 3 - 2 * 27 = - 51
The correct result would be - 51.
If you would like to evaluate x * 0 + y * 0 for x = 3 and y = 2, you can do this using the following step:
x * 0 + y * 0 = 3 * 0 + 2 * 0 = 0 + 0 = 0
The correct result would be 0.
