Q: What grade do kids learn greater than and less than?

Children start comparing groups in Kindergarten under the Common Core standards. In Grade 1 they use the symbols with two digit numbers. In Grade 2 they compare three digit numbers. Algebra style inequalities come later, around Grade 6.

Q: How do you read x < 5 and x ≥ 5?

Read x < 5 as "x is less than five." Read x ≥ 5 as "x is greater than or equal to five," or "x is at least five." The first excludes 5, and the second includes it.

Q: How do you type the greater than or equal to sign?

On Windows, hold Alt and type 242 on the number pad. On a Mac, press Option and period. In Excel formulas, type >= instead of the symbol. In HTML, use the code &ge; to show the sign.

Question 1

What does less than and greater than mean?

Accepted Answer

Less than (<) means the first number is smaller than the second. Greater than (>) means the first number is larger. The wide side of the symbol always faces the bigger number, and the point faces the smaller one.

Question 2

How do you remember which is greater than and less than?

Accepted Answer

Use the alligator trick. The symbol is a hungry mouth that opens toward the bigger number. You can also remember that the point aims at the smaller number, or that < looks like a tilted L.

Question 3

What is the difference between > and ≥?

Accepted Answer

The symbol > means strictly greater than, so the values cannot be equal. The symbol ≥ means greater than or equal to, so they can match. For example, 5 > 5 is false, but 5 ≥ 5 is true.

Question 4

Why does the inequality sign flip when you multiply by a negative?

Accepted Answer

Multiplying by a negative number reverses the order of numbers on a number line. For example, 2 < 5, but negative 2 is greater than negative 5. The order changes, so the symbol must flip to keep the statement true.

Question 5

What grade do kids learn greater than and less than?

Accepted Answer

Children start comparing groups in Kindergarten under the Common Core standards. In Grade 1 they use the symbols with two digit numbers. In Grade 2 they compare three digit numbers. Algebra style inequalities come later, around Grade 6.

Question 6

How do you read x < 5 and x ≥ 5?

Accepted Answer

Read x < 5 as "x is less than five." Read x ≥ 5 as "x is greater than or equal to five," or "x is at least five." The first excludes 5, and the second includes it.

Question 7

How do you type the greater than or equal to sign?

Accepted Answer

On Windows, hold Alt and type 242 on the number pad. On a Mac, press Option and period. In Excel formulas, type >= instead of the symbol. In HTML, use the code ≥ to show the sign.
