The only reason an inequality would change would be because a number is divided or multiplied by a negative number. So if it stayed the same, then it would be because there was no division or multiplication by a negative number. Hope I helped :)

The inequality signs stay the same when you multiply or divide a positive number

They only flip if you multiply or divide a negative number (that is in the divisor place)
