Win in 15 seconds, clear all in 1 minute【24/06/19 19】
Welcome all new and old friends, here is the daily brain-awakening game sent by Dongdong for friends. Starting at 6 a.m. every day, every 1 hour a matchstick game will be delivered to friends. Each consists of 4 questions, and the task of the game is to move the equation and move only one match to make the equation that was not valid before. I look forward to friends to challenge every day to see if you can calculate a question in a few seconds and whether you can clear it in 1 minute.
--------- Level 1---------
【Question 1】The original equation is 61+28=68, which contains the numbers 6, 1, 2, 8, 6, 8 and the operator "+". Among them, 6 and 1 can add a matchstick; The numbers 6 and 8 can reduce a matchstick; There are also 6 and 2 that can be changed into other numbers by moving a matchstick.
--------- Level 2---------
【Question 2】The original equation is 27+75=43, which contains the numbers 2, 7, 7, 5, 4, 3 and the operator "+". Among them, 5 and 3 can add a matchstick; And 7 can reduce a matchstick by these numbers; There are also 2, 5, and 3 that can be changed into other numbers by moving a matchstick.
--------- Level 3---------
【Question 3】The original equation is 91+15=98, which contains the numbers 9, 1, 1, 5, 9, 8 and the operator "+". Among them, 9, 1, and 5 can add a matchstick; The numbers 9 and 8 can reduce a matchstick; There are also 9s and 5s that can be changed into other numbers by moving a matchstick.
--------- Level 4---------
【Question 4】The original equation is 29-11=79, which contains the numbers 2, 9, 1, 1, 7, 9 and the operator "-". Among them, 9 and 1 can add a matchstick; The numbers 9 and 7 can reduce a matchstick; There are also 2 and 9 that can be changed into other numbers by moving a matchstick.
