Win in 15 seconds, clear all in 1 minute【24/07/01 20】
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 42+91=79, which contains the numbers 4, 2, 9, 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.
--------- Level 2---------
【Question 2】The original equation is 65+13=76, which contains the numbers 6, 5, 1, 3, 7, 6 and the operator "+". Among them, 6, 5, 1, and 3 can add a matchstick; The numbers 6 and 7 can reduce a matchstick; There are also 6, 5, and 3 that can be changed into other numbers by moving a matchstick.
--------- Level 3---------
【Question 3】The original equation is 66-91=37, which contains the numbers 6, 6, 9, 1, 3, 7 and the operator "-". Among them, 6, 9, 1, 3 can add a matchstick; The numbers 6, 9, and 7 can reduce a matchstick; There are also 6, 9, and 3 that can be changed into other numbers by moving a matchstick.
--------- Level 4---------
【Question 4】The original equation is 75-31=24, which contains the numbers 7, 5, 3, 1, 2, 4 and the operator "-". Among them, 5, 3, 1 can add a matchstick; And 7 can reduce a matchstick by these numbers; There are also 5, 3, and 2 that can be changed into other numbers by moving a matchstick.
--------- manual bottom line, there is no one behind---------
