what is the least integer greater than – 3 + 0.5 ?
"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 : ( - 3 ) + ( 0.5 ) = - 2.5 on a number line , since we ' re adding + . 5 to a number , the total moves to the right ( so we ' re moving from - 3 to - 2.5 ) . next , the question asks for the least integer that is greater than - 2.5 again , we can use a number line . numbers become greater as you move to the right . the first integer to the right of - 2.5 is - 2 . final answer : a"
add(0.5, negate(3))
