identify situations that demonstrate negative or positive numbers.

Richard, a young professional, started saving money from his salary to reach his goal of having his own house and lot worth 1 million pesos. He consistently deposits 5,000 pesos every month in his bank account. Also, as part of his mid- year and year-end bonuses, an amount of 100,000 pesos was invested in one of the top insurance companies. After four years, he started the construction of his own house and lot. He partially withdraws an amount of 200,000 pesos from his savings account in the bank. While from his investment, he entirely withdraws a total amount of 350,000, which includes the initial capital and the interest earned. However, this amount is still not enough to start the construction. So, he borrows, in the form of a loan, from a bank an amount of 300,000 pesos.

What are the symbols used in comparing integers? Similar to positive numbers, we use the​ (a)   to compare integers. Remember that we use the inequality symbol ​ (b)   for less than and the symbol ​ (c)   for greater than.

For example,

​ ​ (d)   (read as “is less than " ) means that a is to the left of b

​ (e)   (read as “a is greater than b”) means that a is to the right of b.

• “<”
• “>”
• a < b
• a > b
