How do you simplify #8 + 7 [24 - (12 + 2)]# using PEMDAS?

Answer 1

Abigail Allen

Start with the inner-most bracket:

#8+7[24-color(red)((12+2))]#

#8+7[24-14]#

Next, work out the outer or the square bracket:

#8+7color(red)([24-14])#

#8+7[10] => 8+7xx 10#

Multiplication is followed by addition:

#8+color(red)(7xx10#

#=color(red)(8+70)#

#=87#

To simplify 8 + 7 [24 - (12 + 2)] using PEMDAS:

Start with the innermost parentheses: 12 + 2 = 14
Next, perform the subtraction inside the brackets: 24 - 14 = 10
Then, multiply 7 by 10: 7 * 10 = 70
Finally, add 8 to 70: 8 + 70 = 78

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.
