Calculate the following numerical expressions, and work out which result in 200, and which result in a number which is more or less than 200.
The ^ symbol is used for an exponent. 5^2 means 5 to the power of 2, or five squared, or 5 x 5. So 2^3 would be two cubed or 2 x 2 x 2. Don't forget that a - before a number means that it is a negative number.
Some examples:- 4 x 50 = 200; -654 + 432 = -222, which is too low; 9^2 + 11^2 = 81 + 121 = 202, which is too much.

Note the - before 123 making it a negative number.
Subtracting 77 from -123 gives -200, which is 400 less than 200.
2. -99 + 111
Answer: Less
-99 + 111 = 12
Adding 111 to -99 does give a positive answer, but it is only 12, which is 188 less than 200.
3. 11 x 18
Answer: Less
11 x 18 = 198
Multiplying 11 by 18 gives 198, which is 2 less than 200.
4. 2 x (7^2 + 3^2)
Answer: Less
2 x (7^2 + 3^2) = 2 x (49 + 9) = 2 x 58 = 116
Start by working out the expression inside the brackets.
Remember that ^ is used for an exponent.
7^2 = 7 x 7 = 49
3^2 = 3 x 3 = 9
49 + 9 = 58
Then do the last multiplication.
2 x 58 = 116, which is 84 less than 200.
5. 99 + 101
Answer: 200
99 + 101 = 200
Straightforward addition leads to the answer 200.
6. -400 + 600
Answer: 200
-400 + 600 = 200
Note the - before 400 making it a negative number.
Then adding 600 to that gives 200.
7. -20 x -10
Answer: 200
-20 x -10 = 200
Both the numbers for this multiplication are negative, meaning that the resultant product will be positive. So we have 200.
8. 800 / 4
Answer: 200
800 / 4 = 200
Dividing 800 by 4 gives 200.
9. (17 x 37) - (11 x 39)
Answer: 200
(17 x 37) - (11 x 39) = 629 - 429 = 200
This uses both multiplication and subtraction.
Work out the expressions inside the brackets first.
17 x 37 = 629
11 x 39 = 429
Then subtract 429 from 629 to get 200.
10. 2^3 x 5^2
Answer: 200
2^3 x 5^2 = 8 x 25 = 200
Remember that ^ is used for an exponent.
2^3 = 2 x 2 x 2 = 8
5^2 = 5 x 5 = 25
Multiplying 8 by 25 gives 200.
11. 14^2 + 2^2
Answer: 200
14^2 + 2^2 = 196 + 4 = 200
Don't forget that ^ is used for an exponent.
14^2 = 14 x 14 = 196.
2^2 = 2 x 2 = 4.
Adding 4 to 196 gives 200.
12. 5 x (7^2 - 3^2)
Answer: 200
5 x (7^2 - 3^2) = 5 x (49 - 9) = 5 x 40 = 200
Start by working out the expression inside the brackets.
Remember that ^ is used for an exponent.
7^2 = 7 x 7 = 49
3^2 = 3 x 3 = 9
49 - 9 = 40
Then do the last multiplication.
5 x 40 = 200.
13. 3 x 67
Answer: More
3 x 67 = 201
Multiplying 3 by 67 gives 201, which is 1 more than 200.
14. 40000 / 20
Answer: More
40000 / 20 = 2000
Dividing 40000 by 20 gives 2000, which is ten times 200.
15. (13 x 33) - (3 x 43)
Answer: More
(13 x 33) - (3 x 43) = 429 - 129 = 300
This uses both multiplication and subtraction.
Work out the expressions inside the brackets first.
13 x 33 = 429
3 x 43 = 129
Then subtract 129 from 429 to get 300, which is 100 more than 200.
16. 25^2 - 15^2
Answer: More
25^2 - 15^2 = 625 - 225 = 400
Don't forget that ^ is used for an exponent.
25^2 = 25 x 25 = 625.
15^2 = 15 x 15 = 225.
Subtracting 225 from 625 gives 400 which is twice 200.
