\nHere is this week’s problem:<\/p>\n
In the expression\u00a0a\u00a0<\/em>$\u00a0b<\/em>, the $ symbol represents one of the following arithmetic operations on\u00a0a<\/em>\u00a0and\u00a0b<\/em>\u00a0(in the order the variables are shown): addition, subtraction, multiplication, and division. Given that it is not true that\u00a0a<\/em>\u00a0$\u00a0b<\/em>\u00a0=\u00a0b<\/em>\u00a0$\u00a0a<\/em>\u00a0for all possible values of\u00a0a<\/em>\u00a0and\u00a0b<\/em>, a pair of nonzero, non-identical values for\u00a0a<\/em>\u00a0and\u00a0b<\/em>\u00a0is chosen such that\u00a0a<\/em>\u00a0$\u00a0b<\/em>\u00a0produces the same result, no matter which of the operations (under the given constraints) that $ represents. The nonzero value of\u00a0b<\/em>\u00a0that cannot be chosen, no matter the value of\u00a0a<\/em>, is<\/p><\/blockquote>\n
