How do you simplify #(2 + 3) + 42 xx (5 − 3)#?

Answer 1

#89#

Rather than blindly following PEDMAS, BODMSA, etc in whatever you know it, count the number of term first. Each term will simplify to a single answer and these are added or subtracted in the last step.

In each term the order is:

#color(blue)((2 + 3)) color(magenta)(+ 42 xx (5 − 3))" "larr# has 2 terms

#=color(blue)(5) color(magenta)(+ 42 xx 2)#

#= color(blue)(5)color(magenta)(+ 84)#

#=89#

To simplify the expression ( (2 + 3) + 42 \times (5 - 3) ), follow the order of operations (PEMDAS/BODMAS):

Step 1: Solve the parentheses inside the brackets: ( 2 + 3 = 5 ) and ( 5 - 3 = 2 ). Step 2: Multiply: ( 42 \times 2 = 84 ). Step 3: Add: ( 5 + 84 = 89 ).

So, ( (2 + 3) + 42 \times (5 - 3) = 89 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
