21÷3+4+|2 - 3|

21 ÷ 3 + 4 + |2 - 3|

= 7 + 4 + |2 - 3|

= 7 + 4 + |-1|

= 7 + 4 + 1

= 12

|(1/2)(−8)|+|10−4|

|(1/2)(−8)|+|10−4|

= |(-4)| + |6|

= 4 + 6

= 10

To solve the expression 21÷3+4+|2 - 3| step-by-step, follow the order of operations (PEMDAS/BODMAS):

1. First, simplify the absolute value of (2 - 3):
|2 - 3| = | -1 | = 1

2. Then, divide 21 by 3:
21 ÷ 3 = 7

3. Next, add the previous result to 4 and the absolute value:
7 + 4 + 1 = 12

So, the value of the expression 21÷3+4+|2 - 3| is 12.
