Simplfy.(82-60)+ [(-3 x 4)- 36/4]
Do what is in parenthesis first. You get
12 + {12 - 36/4}
Next do what is in the brackets
12 - 36/4 = 48/4 - 36/4 = 12/4 = 3 or
12 - 9 = 3 whichever way you prefer.
Then, you are left with 12 - 3
Hope this makes sense!
To simplify the expression (82-60)+ [(-3 x 4)- 36/4], we can follow the order of operations, which is also known as the PEMDAS rule:
1. Start by simplifying any operations inside parentheses.
Inside the first pair of parentheses, we have: (-3 x 4) which equals -12.
Inside the second pair of parentheses, we have: 36/4 which equals 9.
Now we have (82-60) + (-12-9).
2. Next, perform any multiplication or division from left to right.
There are no multiplication or division operations left.
3. Finally, perform any addition or subtraction from left to right.
Now we have (82-60) + (-21).
Calculating inside the first parentheses, we have: 82-60 = 22.
Substituting back into the expression, we have: 22 + (-21).
To add a positive number to a negative number, we subtract the absolute values and keep the sign of the bigger number, which is -21 in this case.
Therefore, 22 + (-21) equals 1.
So, (82-60)+ [(-3 x 4)- 36/4] simplifies to 1.
