simpla algebra

• 1st of all u need to know that algebra is alot like arithmetic

• it uses the 4 main operations addition subtraction multiplication and division but the only difference is that algebra uses variables or unknown values representing letters

• lets try some the understand ur basic knowleadge

• a+2=3 in this case what does a equal?

second of all

u need to know that algebra can use all 4 operations but division is usually represented as a fraction ex= a/b

also multiplication is specially used in algebra as u see if there is no operation between a letter or a number or a letter and letter multiplication is default . for ex=

ab=a*b

3x=3*x

also remember u also have to find the value of the variable or it is nearly impossible to solve the sum

lets try some question

• 4a+2=10 a=?

• 7x/6=7 x=?

• c+e*5=60 c=?

• sn=16 n=?

• (also remember that the letter value mustn't be in capital always lower case)

• 9k/10=900 k=?

bracket form

in algebra u may have to use brackets to simplify the question or find the answer to a question.

remember in brackets () come 1st [] second and {} and also he brackets come before the the numbers to calculate the brackets 1st is last for example

3d+5/(1w+2*[5-1f])=5\

(1+2=4*[1])= 4. 3*5= 15+5= 20/4= 5 the answer is 5.
