A mini Maths marvel has won millions of fans by solving the C4 ' Countdown ' numbers game at the age of four.
The dad of Acer Gibson posted videos of his son getting the sums right in seconds. The footage showed the schoolboy in front of the TV screen in the living room of their home in Shepshed, near Loughborough.
He is seen beating middle-aged contestants of the Channel 4 show in just 15 seconds. The clips have been watched more than 30m times in just over two weeks.
His dad later posts his little boy answering questions sent to him by Rachel Riley from the show after she views his amazing maths skills online.

She sent Acer his own personal challenges and he solved each of them within the 30-second limit. She joked: "I'll have to watch my back in a few years."
Gibson and partner Holly sensed Acer's potential as a baby. He could count from one to ten and back down again from the age of one.
By the age of two, he had memorised his parents' phone numbers. At three, he was writing down square roots of numbers like 196.
Little more than two weeks ago, Acer stood in front of the TV and he started doing the numbers. His dad recalled: "I wasn't even playing it myself. I said, 'Come on, let's make a video.' I wasn't expecting it to take off."
In the first Countdown TikTok video, posted on December 4, Acer calculates how to reach the target number of 872 with the chosen numbers, 100, 75, 10, seven, six and four, within 30 seconds.
After solving the puzzle, he is seen telling his dad: "Now let's see if they copied us." Neither of the contestants got the answer in time.
Asked about his future plans, Acer said: "Actually I want to do the numbers on the Countdown show. Yeah, I want Rachel Riley's job."
Acer has gone from playing with number-based toys to ploughing through maths workbooks designed for children in years 3, 4 and 5, up to the age of ten.
Even when watching YouTube videos on his tablet featuring characters and storylines in different languages, he has demonstrated an extraordinary memory for his age as he knows the names of all the characters, his father told the Sunday Times.
