The three properties of algebra have been used below to find the number of students in the four sixth-Grade classes which is; 100 students
<h3>How to use properties of algebra?</h3>
There are 3 addition properties and they are associative property, identity property, and commutative property.
Commutative property is one that involves the aspect of just changing the order of the addends. Thus:
26 + 19 + 34 + 21 = 21 + 34 + 19 + 26 = 100 students
Identity Property is just adding a 0 to the number that doesn't change anything. Thus: 26 + 19 + 34 + 21 + 0 = 100 students
Associative property is one that involves just changing the grouping of the addends. Thus:
(26 + 19) + (34 + 21) = (26 + 21) + (19 + 34) = 100 students

2 3/4 that is at least the shortest term
Answer:
steps and answers in the pic..hope u can understand the calculations...
3 plus 3 is 6 but 3 multiplies by 3 is 9, or that 3 plus 3 is 6 plus 3 is 9
