Add [[30,-6],[30,42]]+[[0,4],[4,-12]]

Problem

[[30,−6],[30,42]]+[[0,4],[4,−12]]

Solution

1. Identify the rule for matrix addition, which requires adding the corresponding elements from each matrix.

2. Add the elements in the first row: 30 + 0ƒ*o*r*t*h*e*ƒ*i*r*s(t)*c*o*l*u*m*n*a*n*d6 + 4$ for the second column.

3. Add the elements in the second row: 30 + 4ƒ*o*r*t*h*e*ƒ*i*r*s(t)*c*o*l*u*m*n*a*n*d2 + (-12)$ for the second column.

4. Simplify each sum to find the resulting matrix entries.

30+0=30

−6+4=−2

30+4=34

42−12=30

Final Answer

[[30,−6],[30,42]]+[[0,4],[4,−12]]=[[30,−2],[34,30]]
