1. A psychologist would like to research if the Hope scale (Synder, et al., 1991) scores differ between those living in City A, City B and City C. The 12-item scale consisted of two subscales: a 6-item agency subscale and a 6-item pathways subscales. Scores on each subscale were combined to create total hope score, with higher scores indicating higher levels of hope. The following scores were obtained.

Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
