Question

did anybody understand thiis

Answer 1

Answer:

take the first number as x

then look the numbers the first number is 8 and second one is 9.so what is the relation between 8 and 9 . when we add 1 to 8 we get 9 . then we take 8 as x. next number that means 9 will be x+1 . like this write other two numbers.

In this calender math they are saying about the relation between the sum of the numbers and first number. so add your numbers

The numbers you got is x, x+1 , x+7 and x+8

add all these

x + x+1 + x+7 + x+8

first add all x terms , we get 4x

then add all numbers and we get 1+7+8 = 16

then we got 4x +16

then we have to write 16 as a multiple of 4

there we got 4×4 = 16

the our algebric form turns to 4x + 4×4

taken the common number outside bracket

so we have to write one four from two four outside the bracket

then it is 4( x+4 )

then divide this with 4

that is 4( x+4) ÷ 4 = x+4 ( 4 out side the bracket and the 4 on the division are cancelled)

then subtract 4 from this we get that x+4-4 = x

you have to know that 4 that we divided and subtracted is a fixed number for all the squares contains 4 numbers in it.

hope you understand this calendar math
