10 x ( 6 + 4 ) ÷ ( 7 - 2 ) = r

10 x ( 6 + 4 ) ÷ ( 7 - 2 ) = r

10 x  10  ÷  5  = r

20=r

500

3 + 9 ÷ 3 - 2 x 8 ÷ 4 = t

3 + 9 ÷ 3 - 2 x 8 ÷ 4 = t

3 +    3    - 2 x   2    = t

3 +    3    -    4          = t

True or False

100

True or False : 40- 30 ÷ 2 = 80

False

True Answer: 25

200

True or False: 6 + 27 ÷ 3 = 18

False

True Answer: 15

300

True or False: ( 3 x 4 ) ÷ ( 7 + 9 - 10 ) = 2

True 

400

True or False: ( (10 - 6 + 5 ) ÷ 9 ) x 2 = 4

False 

True Answer: 2

500

True or False: ( 4 + 8 ÷ 2 - 6 ) x 10 = 0

True 

Where does the () go?

100

2 x 8 + 5 - 3 = 23

2 x ( 8 + 5 ) - 3 = 23

200

2 x 15 + 6 - 8 = 36

2 x ( 15 + 6 ) - 8 = 36

300

6 x 8 ÷ 2 - 4 = 20

6 x (8 ÷ 2) - 4 = 20

400

10 x 5 - (2 + 7) x 3 =23

10 x 5 - (2 + 7) x 3 =23

10 x 5 -      (9)  x 3 =23

     50 -       27      = 23

500

60 ÷ 10 + 2 x 4 = n

60 ÷ (10 + 2) x 4 = n

60÷ (12) x 4 = n

5 x 4 = n

20 = n

BEDMAS

100

What does the acronym BEDMAS represent?

Brackets- Exponents- Division- Multiplication- Addition- Subtraction

200

If people do not use BEDMAS rules, what would be the likely mistaken answer they will get, instead of the real solution of 33?     

39 − 9 ÷ 3 × 2 = 

likely they would get an answer of 20

39 − 9 ÷ 3 × 2 = 

30 ÷ 3 × 2 = 

10 x 2 = 20
