Answer 1

1)80-72:12*10=80-60=20

Answer 2

1)4*20-6*10=80-60=20
2)14*5-60=70-60=10
3)80÷5-(4+6)=16-10=6
4)3*20+4=60+4=64

Answer 3

1) Let's solve the first equation step by step:

92:23 * 20 - 72:12 * 10

First, let's simplify the divisions:

4 * 20 - 6 * 10

Next, let's perform the multiplications:

80 - 60

Finally, let's subtract:

80 - 60 = 20

Therefore, the answer to the first equation is 20.

2) Now, let's solve the second equation:

98:7 * 5 - 20 * 3

First, let's simplify the division:

14 * 5 - 20 * 3

Next, let's perform the multiplications:

70 - 60

Finally, let's subtract:

70 - 60 = 10

Therefore, the answer to the second equation is 10.

3) Moving on to the third equation:

4 * 20:5 - (88:22 + 6)

First, let's simplify the division:

4 * 4 - (4 + 6)

Next, let's perform the additions:

16 - 10

Finally, let's subtract:

16 - 10 = 6

Therefore, the answer to the third equation is 6.

4) Lastly, let's solve the fourth equation:

66:22 * 20 + 80:20

First, let's simplify the division:

3 * 20 + 4

Next, let's perform the multiplications:

60 + 4

Finally, let's add:

60 + 4 = 64

Therefore, the answer to the fourth equation is 64.

I hope this helps! Let me know if you have any further questions.
