Question

I do n't understand please help?

Answer 1

1) 109 Explanation: do what is in the () first so 3^2 is going to turn into 9 which is the equation is now going to be 145-(9x4). 9x4 is 36 so it is 145-36 which gives you 109.
2) 52 Explanation: 45 divided by 9 is 5 then 5 times 12 gives you 60. equation now is 60-8 which equals 52.
3) 4 Explanation: 3 times 4 is 12. equation now is 2^2+12-12. all is left is 2^2 which is 4.
4) 89
5)111
6)72

Answer 2

1. 145-(3squared times 4)=109

2. 45 divided by 9 times 12-8= 52

3. 2 squared +3 times 4-12= 4

4.[155-(3 times 9) times 2] -12= 89

5. [(6 times 2) +(5 times 5) times 3= 111

6. 2 times {15+[24-(1.5 times 2)]}= 72

Explanation:

(BOMDAS) brackets, operations, multiplication, division, addition, subtraction

1. (deal with the brackets first)

3 squared=9 then times by 4 =9*4=36

so..

145-36=109

2. (start with division )

45 divided by 9 =5

so

5 times 12-8= 52

3. 2 squared = 4

4 times 3 =12

so

4+12-12 =4

4. (deal with brackets first)

3 times 9 = 27

27 times 2= 54

155-54= 101

101-12=89

5. (deal with the brackets first)

6 times 2 =12

5 times 5=25

so 12+25= 37 times 3 = 111

6. (deal with the brackets first)

1.5 times 2= 3

24-3= 21

15+21=36

2 times 36= 72

hope this helps!!!
