Multiply or Divide the Inequalities on both the sides with the same Positive Number.Some of the tricks that don’t affect the direction of inequalities are as listed below

While dealing with Inequalities Problems you should pay attention to the inequality sign direction. Solving Inequalities is similar to solving equations. In Inequality, less than symbol will always be pointed towards the lesser value, and the symbol consisting of two equal length strokes connecting in an acute angle at the left.Īlligator mouth opens towards 10 since it wants to et 10 fishes rather than 6 fishes. Less than symbol is placed between two values when the first value is less than the second value. The symbol used to represent greater than is “>” and less than is “5, here 8 is greater than 5 Greater than and Less than Symbols denotes the inequality between two values. Greater than and Less than Symbols – Definition Using Symbols will help you save time and space and users can understand them easily. Refer to the entire article to learn about Greater than and Less than Symbols, Notations, and Tricks to remember them easily. If a number is bigger than another symbol greater than symbol is used and when a number is less than the other number less than symbol is used. One could refer to this image.Greater than and Less than Symbols are used to compare any numbers.

I did not include interval notation as I would need to include the concept of infinity. Adding these with inequalities would definitely increase the difficulty levels.įor cases like -1 ≤ 10 you do not necessarily need ≤ when < is enough. Natural extensions would include multiplication, division, fractions, exponents, square roots and more. Q3) (7 + 5) ≤ (20 - 8) or (7 + 5) ≥ (20 - 8) or 12 ≤ 12Īnother Aligator Learning Aid For Inequalitiesįor simplicity, the exercise problems deal with addition and subtraction. The math notation would be (7 + 11) ≥ 15 or 18 ≥ 15.įor questions 1 to 5, use the less than sign (≤) or the greater than sign (≥) when filling in the blanks. In the previous section there was the inequality 7 20.Īdding the numbers 7 and 11 gives 18 which is greater than or equal to 15. The symbol for the less than or equal to sign is ≤ and the greater than or equal sign to is indicated by ≥. The numbers can be equal on top of being either less than or greater than. Q5) 10 _ 2 _ -1 Less Than Or Equal To Signs & Greater Than Or Equal To SignsĪn extension of the above cases would be adding on an equal sign. A negative number that is more negative is father away from zero.įor questions 1 to 5, use the less than sign () when filling in the gray area. When dealing with numbers, remember that the negative number closest to zero is the larger number. Another way to look at it is that the symbols is like a mouth where the smaller number tries to eat the bigger number (see image below). You can look at these inequality symbols like arrows where the larger number 'points' at the smaller number. With the less than sign ) we deal with quantities that are not equal. The Less Than Sign & The Greater Than Sign

The Less Than Sign & The Greater Than Sign.

This post is about comparison signs such as the less than sign (), the less than or equal to sign (≤) and the greater than or equal to sign (≥).
