A schoolboy was caught by his mother using Amazon Alexa to cheat on his maths homework. Allen Ramirez, eight, asked the audio virtual assistant smart speaker subtraction questions. Mum Iris Molina filmed Allen, a third-grader, in his bedroom doing his homework and whispering questions to Alexa. Allen is heard asking: "Alexa? What is 97 minus 68?" - to which the device responds in whispers "97 minus 68 is 25." SWNS
