Step-5

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 u = 1, v = -1, w = 2 & x = -2	\$ u + v - w + x \$
2	Now substitute "\$u,v,w,x\$" values in the expression	\$ 1 + (-1) - 2 + (-2) \$
3	After simplification we get	\$ 1 - 1 - 2 - 2 \$
4	After simplification we get, we get	\$ -4 \$
5	Answer	C = \$ -4 \$

Steps

Problem

Solution

Determine the value of an expression at
u = 1, v = -1, w = 2 & x = -2

\$ u + v - w + x \$

Now substitute "\$u,v,w,x\$" values in the expression

\$ 1 + (-1) - 2 + (-2) \$

After simplification we get

\$ 1 - 1 - 2 - 2 \$

After simplification we get, we get

\$ -4 \$

Answer

C = \$ -4 \$
