Iknow the answer to number 7 but i just want to see if you guys know it

Plugging 10 for k in the expression gives us
We simplify this expression to  
251 is your answer

1.  9(3)+3 = 27+3 = 30
2. 9() = 9(4096) = 36864
3. 9-6+3 = 6
4. 6(5)+30 = 30+30 = 60
5. 6() = 6(512) = 3072
6. ()+84 = 512+84 = 596
7. 200+51 = 251
8. 3(18)+ = 54+324 = 378
9. 12(24)-36 = 288-36 = 252
10. 4(11+90)+10 = 44+280+10 = 334
11. 8-8 = 0
12.14(95)-1264+1 = 1330-1264+1 = 66+1 = 67

Ihave, but this question is gonna probably get deleted.
