## algebra

• If '&' denotes one of the two arithmetic operations, addition or multiplication, and if k is an integer, what is the value of 3 & k?
(1) 2 & k = 3
(2) 1 & 0 = k

2. Good post? |
Statement 1 is sufficient. (3&k=4)

Statement 2 is not sufficeint. (3&k=4 or 3&k=0)

3. Good post? |
A it is

4. Good post? |
shouldn't it be D?

A is sufficient as given by lsr and givemeanid

B is also sufficient because:

1&0=k
given that k is an integer, '&' cannot be multiplication because then k=0
therefore, '&' has to be addition and k=1

am i wrong?

Integers: ....-3,-2,-1,0,1,2,3......
Negative integers: .....-3,-2,-1.
Positivie integers: 1,2,3......
Non-negative integers: 0,1,2,3.....

how could A be sufficient if & indicates multiplication or addition

2 + k = 3 , k=1
2 * k = 3 , k=3/2

different values for K, result in different values for 3 & k

am i not thinking right?

7. Good post? |
3/2 is not an integer, as K must be an integer, it can't be 3/2

8. Good post? |

Agree to the above explanations.

9. Good post? |
thanks for the clarification. i've had a running confusion about the personality of 0

thank you Gnid, that makes sense now.
