Problem: what is the least integer greater than – 4 + 0.5 ?
Rationale: "this question is just about doing careful arithmetic and remembering what makes a numberbiggerorsmallercompared to another number . first , let ' s take care of the arithmetic : ( - 4 ) + ( 0.5 ) = - 3.5 on a number line , since we ' re adding + . 5 to a number , the total moves to the right ( so we ' re moving from - 4 to - 3.5 ) . next , the question asks for the least integer that is greater than - 3.5 again , we can use a number line . numbers become greater as you move to the right . the first integer to the right of - 3.5 is - 3 . final answer : a"
