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. , inequality, greater than or equal to, inequality, less than or equal to ( ), parentheses, calculate expression inside first, brackets, calculate.

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. Beginning Gesture with your arms wide as you say in a loud voice, 'greater than', arms close together as you say in a whisper voice, 'less than,' and hold arms parallel to form an equal sign as you say, 'equal to.' Instruct students to define the vocabulary in their home language (L1). 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). In this case, symbols are used to compare numbers by size. 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.

Combination of greater than (>) and less than (<) signs make the operator sign not equal to <>.

Therefore, it implies that either five or six are greater or equal to two. This equation shows a greater sign, but it also has a half equal sign.

The Less Than Sign & The Greater Than Sign 6 Not Equal Sign (<>) to Compare Numerical Values. The equal to or less than and equal to signs simply feature a half equal sign symbol under them.

Less Than Or Equal Signs & Greater Than Or Equal Signs.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 (≥).

Symbol greater than less than equal to
