First, she squares it.
Then she subtracts 15 from this result.
Finally she doubles this latest result, arriving at the value 20.
What number did she pick?
First try to work the problem. Check your problem solving strategy and answer below:

METHOD 1: Use algebra.
Let x be a number less than 4. An equation representing the three successive operations is: 2(x^2 - 15) = 20. Distributing to remove parentheses gives: 2x^2 - 30 = 20. Adding 20 to both sides: 2x^2 = 50. Dividing by 2: x^2 = 25. The two numbers whose square is 25 are +5 and -5. Of these, only -5 is less than 4. The answer is -5.
METHOD 2: Work backwards.
The 3rd operation is DOUBLING. To arrive at 20, Olivia had begun this step with 10. 
The 2nd step was SUBTRACTING 15. To achieve the result of 10, she had to begin the step with 25.
The 1st step was SQUARING. Granted, squaring 5 results in 25, but 5 is NOT less than 4. Ah, squaring -5 ALSO results in 25 and -5 IS less than 4. So, Olivia had begun with -5.
