In this lesson, we will learn how to add and subtract matrices.
Q1:
Suppose the sum π΄ + π΅ + πΆ makes sense. We also know that π΄ has 2 rows and πΆ has 3 columns. What can we say about matrix π΅ ?
Q2:
Let π be a 2 Γ 3 matrix whose entries are all zero. If π΄ is any 2 Γ 3 matrix, which of following is equivalent to π΄ + π ?
Q3:
Given that π is the zero matrix of order 2 Γ 3 , find the value of ο 2 6 4 4 3 β 8 ο + π .
