Represent statement as integers

Negative numbers on the number line Zero Negative integers Positive integers The numbers –1, –2, –3, … (to the left of zero) are called negative integers The numbers 1, 2, 3,… (to the right of zero) as positive integers. The new set of numbers …, -3, -2, -1, 0, 1, 2, 3,… are called Integers. ‘–’ symbol in front of a number is read as 'negative' or 'minus'. For example, –5 is read as negative 5 or minus 5. A number without a sign is considered as a positive number. For example, 5 is considered as +5.

Represent statement as integers The following statement represents positive and negative integers Positive integer statement Negative Integer statement 50 m high means (+50) 150m low means (-150) 250m up means (+250) 175m down means (-175m) Rs 200 deposit means (+Rs 200) Rs 300 withdrawal means (–Rs 300) 75m forward means (+75m) 200m backward means (-200m) year 2018 AD means (+2018) year 500 BC means (-500)

Represent statement as integers The following statement represents positive and negative integers Positive integer statement Negative Integer statement profit or gain of Rs 500 means (+Rs 500) loss of Rs 200 means (–Rs 200) 50m above sea level means (+50m) 200m below sea level means )(-200m) Rise of 200 C means (+ 200 C) fall of 100 C means (- 100 C) Rs 500 earning means (+ Rs 500) Rs 200 spending means (–Rs 200)

Try these Represent the statement below as integer 2 floors above the ground floor A deposit of Rs 200 500m below sea level A Profit of Rs 500
