How do you simplify #21 - 8 times 4.5 + 60#?

Answer 1

#45#

Here, #21-8 xx 4.5 + 60# # = 21 - 36 + 60# # = 81 - 36# # = 45# Note : While simplifying, we should do the calculations according to the formula #i.e.# BODMAS in which: #-># B = Bracket (start with anything inside brackets, going from left to right). #-># O = Orders (numbers involving powers or square roots) #-># D = Division #-># M = Multiplication #-># A = Addition #-># S = Subtraction

To simplify the expression 21 - 8 * 4.5 + 60, follow the order of operations (PEMDAS/BODMAS): First, perform multiplication and division from left to right, then addition and subtraction from left to right.

21 - 8 * 4.5 + 60 = 21 - (8 * 4.5) + 60 = 21 - 36 + 60 = -15 + 60 = 45
