Introduction to solving for math arrays:
Solving for math arrays is nothing but find the value of the array or we have to perform the operations using the arrays. Math arrays are nothing but an arrangement of a set of numbers or objects. We will represent the arrays in the form of rows and columns. Here we are going to see solving the math problems using math arrays.

Solving math arrays:
Solving math arrays mean we can perform the addition, subtraction, multiplication operations. Or we have to find the value of the math array.
Solving the math arrays for addition:
First we will see addition operation for `2xx 2`
`[[1,2],[3,4]][[9, 2],[5, 6]]`
Solution:
`[[1,2],[3,4]][[9, 2],[5, 6]]`
We have to add the arrays directly. Like add the fist element of the row in the first array with first element of the row in the second array. So we will get
`[[10,4],[8,10]]`
Solving for subtraction of math arrays:
`[[10,20],[9,8]][[21, 15],[12, 15]]`
We have to subtract the arrays directly. Like subtract the fist element of the row in the first array with first element of the row in the second array. So we will get
`[[-11, 5],[-3,-7]]`
Solving math arrays: Finding the value of 2 dimensional arrays:
` [[-1, 8],[9,2]]`
Solution:
` [[-1, 8],[9,2]]`
= (-1 `xx ` 2) - (8 `xx ` 9)
= -2 - 72
= -74
Having problem with The Means Test keep reading my upcoming posts, i will try to help you.
Solving math arrays: Finding the value of 3 dimensional arrays:
Consider the following 3 - dimensional array
`[[a,b, c],[c,d, e], [f, g, h]]`
If we want to find the value of this mean we have to expand this array.
= a (d h - e g) - b (c h - ef ) + c (c g - d f)
Example:
Find the value of the following array: `[[1,2, 5],[2,6, 9], [8, 3, 4]]`
Solution:
Given array is `[[1,2, 5],[2,6, 9], [8, 3, 4]]`
= [1 ((6 X 4) - (9 X 3))] - [2 ((2 X 4) - (9 X 8))] + [5((2 X 3) - (6 X 8))]
= [1 (24 - 27)] - [2(8 - 72)] + [5 (6 - 48)]
= [1 (-3) - 2(- 64) + 5 (- 42)]
= -3 + 128 - 210
= - 85
