Answer: 966
Step-by-step explanation:
(12 x 13 + 18 x 45)
Apply BODMAS rule (BODMAS is a short form for Brackets, Of, Division, Multiplication, Addition and Subtraction)
So, do your multiplication task first
(12 x 13 + 18 x 45)
= (156 + 18 x 45)
= (156 + 810)
Now, do your addition task
= 156 + 810
= 966
