Stop cheating and start asking for help FROM YOUR TEACHER. If this really is for your brother, be a good brother and help him by speaking with your parents and/or his teacher and get him the extra help he needs. Getting point whores to do your (or his) homework for you isn’t ultimately going to help you with anything. Not to mention the fact that its blatant cheating.

2*2*2 = 8

4+9 = 13

25 + 10 +1 = 36

8 * (2 + N)

3 – (5 * N) [parentheses are optional here)

9.45

15/24 + 14/24 = 29/24 = 1 and 5/24

1.3216

19/8 * 23/4 = 437/32 = 13 and 21/32

It is really simple

Look at how you were told to do the last set this one is exactly the same.

And use this ‘^2’ so signify squared. It is on the six key

2. 8

3. 13

4. 36

1. 8x(N+2)

2. (Nx5)-(Nx3)= (Nx2)

3. 9.45

4. Not using paper

5. 1.32

6. not using paper

And this is really simple. I did it in my head in like 5 minutes total
