First, the formulas of greater than sign and less than sign.
Tip refers to who is small, and the tip is smaller than the symbol on the left and larger than the symbol on the right.
Second, the nursery rhymes of greater than and less than.
The tip is less than the number on the left.
The tip is greater than the number on the right.
Less than sign, greater than sign.
The top pair leans to both sides.
Three, greater than and less than the small hand method
Raise your right hand and put it before your eyes. The shape of your right hand is larger than the symbol. Raise your left hand and put it in front of your eyes. The shape of your left hand is smaller than the symbol.
Four. Brief introduction of greater than sign and less than sign
The greater than sign is the symbol of inequality operation in mathematics. The greater than sign is widely used in arithmetic, and it is a must-learn content in primary schools. Less than sign is one of the symbols of inequality operation in mathematics.
Harry Otto, a British mathematician, first used the symbol ""in his book Usage Analysis, but it was not published until after his death 163 1 year.
Use of greater than sign and less than sign
In mathematics, the greater than sign () and the less than sign () are symbols used to indicate mathematical comparison, indicating whether one numerical value is greater than or less than another. The use of these symbols in mathematics includes but is not limited to the following situations:
1, compare values
The greater than sign (>) is used to indicate whether one value is greater than another. For example, a > B means that a is greater than B.
2. Compare the size relationship
Less than sign (
3. Inequality
Greater than sign and less than sign are often used to represent inequalities, such as x >；; 5 means that x is greater than 5, y.
4. Symbols in mathematical expressions
The greater than sign and the less than sign are also used to construct mathematical expressions, which can be combined with the equal sign (=), such as greater than or equal to (≥) and less than or equal to (≤).
These symbols are very important for describing the relationship between values, solving inequalities and deriving mathematical equations. In mathematics, they are widely used in algebra, geometry, calculus, probability statistics and other mathematical branches.
