if [ x ] is the greatest integer less than or equal to x , what is the value of [ - 11.6 ] + [ 13.4 ] + [ 12.7 ] ?
"you are asked what the closest lesser integer value to [ x ] is . [ - 11.6 ] = - 12.0 [ 13.4 ] = 13.0 [ 12.7 ] = 12.0 therefore , answer is : - 12.0 + 13.0 + 12.0 = 13.0 option a ."
subtract(add(13.4, 12.7), 11.6)
