Have you ever thought of celebrating your birthday and age candle on your birthday cake 🎂has same number always.You sleep at night and next day you find your house has one more floor added 😇above it,it would surprise🤔 you and your parents as well.
➡️Your age will not remain same on your next birthday . Your Age will increase.
➡️Your house will have same number of floors it will not increase each day.
Let me introduce you to two new freind :
Are you familiar🙄 with them .
Your Age is variable and number of floors of your house is Constant.
Constant is which doesn’t change with time or context ,Variable changes with time or context.
x,y,z are example of variable while 1,2,3 are constant . X as variable can hold the values of 1,2 .
Variables have different degree and so variables can have values too.
x=3+2 will have value x as 5.
x-4 =1 will be solved by moving 4 to right side and we get x=4+1 that is 5 .
We will come to linear equation in one variable in next post, Playing with Variables ,Constant and Children Imagination -2 .
