Question

86-15•4+29 24•3-12•4 (16•5-20):6

Answer 1

86-15*4+29=55
24*3-12*4=24
（16*5-20）: 6 =10

Answer 2

85-15•4+29=85-60+29=54
24•3-12•4=92-48=44
(16•5-20):6=(80-20):6=60:6=10

Answer 3

Let's break down and solve the given mathematical expression step by step:

1. Evaluate within parentheses:

   • (16•5 - 20) = 80 - 20 = 60

2. Divide:

   • 60 : 6 = 10

3. Multiply:

   • 24•3 = 72
   • 12•4 = 48

4. Subtract and add:

   • 86 - 15•4 + 29 = 86 - 60 + 29 = 55

5. Multiply:

   • 10 * 10 = 100

6. Subtract:

   • 100 - 72 + 48 = 76

So, the final result of the given expression is 76.
