Cerebral palsy and geomantic omen
100 people took part in the parade.
-21-1-2 = 20-2 =10 people.
The result is that there are 10 people in each row and column: 10 × 10 = 100 people.
Adding one line horizontally and vertically is 2 1 person. Because there is an overlap, there are 1 1 person in the horizontal row and 1 1 person in the vertical row.
Now * * *11×11=12/person.
It turned out to be121-21=100 people.
Property 1
Adding (or subtracting) the same algebraic expression on both sides of the equation still holds.
If a=b
Then a+c=b+c
Attribute 2
When both sides of the equation are multiplied or divided by the same non-zero algebraic expression, the equation still holds.
If a=b
Then there is a c = b c
Or a÷c=b÷c (c≠0).
