We can write the whole number 159 in expanded form as follows: 159 = (1 x 100) + (5 x 10) + (9 x 1). Decimals can also be written in expanded form. Expanded form is a way to write numbers by showing the value of each digit.This is shown in the example below.Example 4: Write each decimal in expanded form.e can write the whole number 159 in expanded form as follows: 159 = (1 x 100) + (5 x 10) + (9 x 1).

Simply put, an addend is one of the numbers in an addition math sentence that is being added. In the math sentence 2+3=5 the numbers 2 and 3 are addends while the number 5 is the sum.Often, when we are teaching young learners about addition sentences we refer to part/part/whole.So, in the above example, 2 and 3 are parts and they add together for the whole of 5.A fancier way of saying part/part/whole would be addend/addend/sum. All of this is important because we are trying to get young learners to think algebraically.o, in the above example, 2 and 3 are parts and they add together for the whole of 5.
