Inequalities with addition and subtraction statements

Lesson

Sometimes we need to check if two equations are equal to each other or not. If they aren't, we need to identify if the statement on the left is less than (<) or greater than (>) the statement on the right. Let's see how we can check this:

Choose from the selection of signs $=$=, $<$<,$>$> to complete the following statement:

$11+30\editable{}11+27$11+3011+27

Choose from the selection of signs $=$=, $<$<, $>$> to complete the following statement:

$38\editable{}73-15$3873−15

Choose from the selection of signs $=$=, $<$<, $>$> to complete the following statement:

$87-27\editable{}22+1$87−2722+1

Know how many ones, tens, and hundreds are in whole numbers to at least 1000.
