Solution
A−B=⎡⎢⎣204628246⎤⎥⎦−⎡⎢⎣84−20−20226⎤⎥⎦A−B=⎡⎢⎣2−80−44+26−02+28−02−24−26−6⎤⎥⎦A−B=⎡⎢⎣−6−46648020⎤⎥⎦(A−B)+C=⎡⎢⎣−6−46648020⎤⎥⎦+⎡⎢⎣8200−2−6−84−10⎤⎥⎦=⎡⎢⎣−6+8−4+26+06+04−28−60−82+40−10⎤⎥⎦=⎡⎢⎣2−26622−86−10⎤⎥⎦∴(A−B)+C=⎡⎢⎣2−26622−86−10⎤⎥⎦
A−B=⎡⎢⎣204628246⎤⎥⎦−⎡⎢⎣84−20−20226⎤⎥⎦
A−B=⎡⎢⎣2−80−44+26−02+28−02−24−26−6⎤⎥⎦
A−B=⎡⎢⎣−6−46648020⎤⎥⎦
(A−B)+C=⎡⎢⎣−6−46648020⎤⎥⎦+⎡⎢⎣8200−2−6−84−10⎤⎥⎦
=⎡⎢⎣−6+8−4+26+06+04−28−60−82+40−10⎤⎥⎦
=⎡⎢⎣2−26622−86−10⎤⎥⎦
∴(A−B)+C=⎡⎢⎣2−26622−86−10⎤⎥⎦
