Title: Determine the value of an expression

Grade: 6-b Lesson: S4-L3

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Determine the value of an expression at x = 1/6 & y = -1/6,	\$ x + y + xy \$
2	Now substitute "\$x,y\$" values in the expression	\$ \cancel(1/6) + \cancel((-1/6)) + (1/6)(-1/6) \$
3	After cancellation we get	\$ (1/6)(-1/6) \$
4	After Multiplicaion we get	\$ -1/36 \$
5	Answer	A = \$ -1/36 \$

Steps

Problem

Solution

Determine the value of an expression at
x = 1/6 & y = -1/6,

\$ x + y + xy \$

Now substitute "\$x,y\$" values in the expression

\$ \cancel(1/6) + \cancel((-1/6)) + (1/6)(-1/6) \$

After cancellation we get

\$ (1/6)(-1/6) \$

After Multiplicaion we get

\$ -1/36 \$

Answer

A = \$ -1/36 \$
