In the expression (1 + (1 + 1) * 2) * 2, Sarah may erase one open parenthesis (" ( ") and one close parenthesis (" ) " ), or she may erase nothing. Find the least possible value of the resulting expression.
If she erases nothing
(1 + (1 + 1) * 2) * 2 = (1 + 2*2) * 2 = 10
Other possibilities
1 + (1 + 1 *2) *2 = 1 + (3)*2 = 7 = least possible value
1 + (1 + 1) * 2 * 2 = 1 + 2 * 2 * 2 = 9
(1 + 1 + 1 *2) *2 = ( 2 + 2)*2 = 4 * 2 = 8
(1 + 1 + 1) * 2 * 2 = (3) * 2 * 2 = 12
Thx Chris it's correct
OK.....!!!
