2,323 items
Given:
Question:
How many total items will be in the collage? Use mental math to solve explain your thinking.
The Process:
From the information above, let us create a suitable diagram as follows:
[tex] \boxed{23} \boxed{23} \boxed{23} \ ... \ \boxed{23} \boxed{23} [/tex]
1 2 3 ... 100 101
To obtain the total amount of items that will be in the collage, we multiply 101 by 23.
[tex]\boxed{ \ 101 \times 23 = \ ? \ }[/tex]
Prepare 101 as 100 + 1, rearrange the diagram.
[tex] \boxed{23} \boxed{23} \boxed{23} \ ... \ \boxed{23} \boxed{23} + \boxed{23} [/tex]
1 2 3 ... 99 100 + 1
Now, let us calculate.
[tex]\boxed{ \ = (100 + 1) \times 23 \ }[/tex]
[tex]\boxed{ \ = (100 \times 23) + (1 \times 23) \ }[/tex]
[tex]\boxed{ \ = 2300 + 23 \ }[/tex]
[tex]\boxed{\boxed{ \ = 2323 \ }}[/tex]
Thus there are 2,323 total items will be in the collage.
