We need to find the value of 4 + 1 . We add the numbers by counting dots. We use 4 dots to show the number 4 . We use 1 dot to show the number 1 . To find 4 + 1 , we count the total number of dots. 4 ∙ ∙ ∙ ∙ + 1 ∙ 5 ∙ ∙ ∙ ∙ ∙ Total number of dots is 5 , hence 4 + 1 = 5 .

We need to find the value of 0 + 2 . We add the numbers by counting dots. We do not use any dots to show the number 0 . We use 2 dots to show the number 2 . To find 0 + 2 , we count the total number of dots. 0 + 2 ∙ ∙ 2 ∙ ∙ Total number of dots is 2 , hence 0 + 2 = 2 .

We need to find the value of 3 + 4 . We add the numbers by counting dots. We use 3 dots to show the number 3 . We use 4 dots to show the number 4 . To find 3 + 4 , we count the total number of dots in the last row. 3 ∙ ∙ ∙ + 4 ∙ ∙ ∙ ∙ 7 ∙ ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 7 , hence 3 + 4 = 7 .

We need to find the value of 3 + 6 . We add the numbers by counting dots. We use 3 dots to show the number 3 . We use 6 dots to show the number 6 . To find 3 + 6 , we count the total number of dots in the last row. 3 ∙ ∙ ∙ + 6 ∙ ∙ ∙ ∙ ∙ ∙ 9 ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 9 , hence 3 + 6 = 9 .

We need to find the value of 5 + 2 . We add the numbers by counting dots. We use 5 dots to show the number 5 . We use 2 dots to show the number 2 . To find 5 + 2 , we count the total number of dots. 5 ∙ ∙ ∙ ∙ ∙ + 2 ∙ ∙ 7 ∙ ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 7 , hence 5 + 2 = 7 .

We need to find the value of 3 + 6 . We add the numbers by counting dots. We use 3 dots to show the number 3 . To find 3 + 3 , we count the total number of dots in the last row. 3 ∙ ∙ ∙ + 3 ∙ ∙ ∙ 6 ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 6 , hence 3 + 3 = 6 .

We need to find the value of 0 + 8 . We add the numbers by counting dots. We do not use any dots to show the number 0 . We use 8 dots to show the number 8 . To find 0 + 8 , we count the total number of dots in the last row. 0 + 8 ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ 8 ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 8 , hence 0 + 8 = 8 .

We need to find the value of 6 + 3 . We add the numbers by counting dots. We use 6 dots to show the number 6 . We use 3 dots to show the number 3 . To find 6 + 3 , we count the total number of dots in the last row. 6 ∙ ∙ ∙ ∙ ∙ ∙ + 3 ∙ ∙ ∙ 9 ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 9 , hence 6 + 3 = 9 .

We need to find the value of 1 + 7 . We add the numbers by counting dots. We use 1 dot to show the number 1 . We use 7 dots to show the number 7 . To find 1 + 7 , we count the total number of dots in the last row. 1 ∙ + 7 ∙ ∙ ∙ ∙ ∙ ∙ ∙ 8 ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ Total number of dots is 8 , hence 1 + 7 = 8 .
