No Calculator: What is the 

sqrt(16)

4

100

? = 81

100

25 - 4*5 = 25-20 = 5

100

If the rock fell for 3 seconds, how far did it fall?

d=15t^2 

d = 15*9=135 feet

100

Solve for x: 

2x + 8 = 20

6

200

No calculator: What is the

sqrt(64)

8

200

sqrt81+sqrt16-3(sqrt9+sqrt49)=

9+4-3(10) = 9 + 4 - 30 = 13 - 30 = -17 (must have negative sign) 

200

6+64=70

200

If the rock fell for 576 feet, how long did it fall?

d=16t^2

t^2=36,   so t = 6 seconds

200

No Calculator: What is 

3^4=

3*3*3*3=81

300

No Calculator: What is the 

sqrt(121)  - sqrt(144)

-1

300

sqrt100-sqrt81-sqrt64-sqrt1=

10 - 9 -8 - 1 = 

    1   - 8 - 1 

       - 7  - 1 = -8

300

100-50div2-10*2=

100-25-20=55

300

How far did a rock that fell for 4 seconds fall? using : 

d=9t^2

d = 

9*16=144

300

What is 

8x+4=8

8x=4, so x=0.5 or 

1/2

400

No Calculator: Simplify, what is the 

sqrt(64/16)

8/4 = 2

400

f(x)=4x+5; f(9)=?

4(9) + 5 = 36 + 5 = 41

400

3^3div3*1-100=

9-100 = -91

400

How long did a rock fell if it fell for 729 feet. Using: 

d=9t^2


t^2=81; SO , t=9 seconds

400

What is the sum of -56 + 18?

- 56 + 18, subtract them and keep the sign of 56, so = -38

500

No Calculator: What is

sqrt(100)+sqrt(16)-sqrt(400)=

10 + 4 - 20 = -6

500

f(2) - f(9) = 

when 

f(x)=x^2-11

2^2-11 = -7

9^2-11= 81 - 11 = 70

-7-70=-77

500

15div5*2+3(10-12div4)=
