Subtracting+Matrices

Make sure you follow these wonderful rules before you start the problem!
 * __//Rules//__:**


 * **The dimensions have to be equal**
 * **If you're subtracting a negative, be sure to make it addition(positive). This is a common mistake.**
 * **Subtract corresponding entries**

[4 8] - [3 4] = [1 4] [2 6] - [-3 6] = [5 0]
 * __//Examples//__:**

1.) First, check if the problem is possible. See "Rules" for more details. 2.) Take 4, and subtract 3 (its corresponding entry) to get 1. 3.) Take 8, minus 4, and get 4. 4.) Take 2, subtract -3, and get 5. You got the positive 5 by the subtracting negatice rule. 5.) Take 6 minus 6, which gives you a lonely 0. 6.) Your matrix is complete! It should turn out like this: [1 4] [5 0]

Problem __cannot__ be subtracted because dimensions are different: [2 0] - [1] [3 4] - [5]
