Calculator Techniques Type of Problem

Expanding

Finding the remainder of an two equations

Arithmetic Progression- Finding the value at a given term

Arithmetic Progression- Finding the nth term with a given value

Arithmetic Progression- Finding the common difference

Arithmetic Progression- Finding the sum. Geometric Progression- Finding the value at a given term

Calculator Technique 1. Input given equation 2. Assign values of X and Y using CALC 3. Input choices 4. Assign values of X and Y 5. The equation with the same answer as the given is the correct choice. 1. Solve the value of X of the divider. Equate the equation to zero. (Ex. 2X+3=0 which means x=-3/2) 2. Input the dividend. 3. Substitute the value of X from the divisor to the dividend using CALC. 1. Press Mode 3,2 2. Assign nth term under X. 3. Assign values at nth under Y. 4. Input (nth)ŷ  To input ŷ press Shift>1,5(reg),5(ŷ) 1. Press Mode 3,2 2. Assign nth term under X. 3. Assign values at nth under Y. 4. Input ( ẋ)value  To input ẋ press Shift>1,5(reg),4(ẋ) 1. Press Mode 3,2 2. Assign nth term under X. 3. Assign values at nth under Y. 4. Input B  To input B press Shift>1,5(reg),2(B) 1. Press Mode 3,2 2. Assign nth term under X. 3. Assign values at nth under Y. 4. Input on calculator: Ʃ(X ŷ, first nth, last nth) 1. Press Mode 3,6 2. Assign nth term under X. 3. Assign values at nth under Y. 4. Input (nth)ŷ 

To input ŷ press
