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 Inequalities Notesįor 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 ≥. And in latex, you can use the direct less than symbol as a command to represent. The numbers can be equal on top of being either less than or greater than. Less than is the inequality mathematical symbol that is on your keyboard. 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 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 (≥).
