I see the image you’ve uploaded is a math table with calculations for addition and subtraction of decimals. Let's break down the calculations for the given values:

Given:

• a values: 13.05, -8.59, -14.152
• b values: -6.17, 37.16

The table requires us to find:

1. a + b (the sum of the numbers in each column)
2. a - b (the difference between the numbers in each column)

Let's calculate:

1. For the first column:

   • a = 13.05, b = -6.17
   • $a + b = 13.05 + (-6.17) = 6.88$
   • $a - b = 13.05 - (-6.17) = 13.05 + 6.17 = 19.22$

2. For the second column:

   • a = -8.59, b = 37.16
   • $a + b = -8.59 + 37.16 = 28.57$
   • $a - b = -8.59 - 37.16 = -45.75$

3. For the third column:

   • a = -14.152, b = 37.16
   • $a + b = -14.152 + 37.16 = 23.008$
   • $a - b = -14.152 - 37.16 = -51.312$

Updated Table:

a	b	a + b	a - b
13.05	-6.17	6.88	19.22
-8.59	37.16	28.57	-45.75
-14.152	37.16	23.008	-51.312

Let me know if you'd like further clarifications or if you have additional questions!

Here are 5 related questions for further practice:

1. How would the results change if the values of a or b were positive in the second row?
2. How do you handle decimal points when adding or subtracting?
3. Can you explain how to round decimals when calculating sums and differences?
4. How do you perform addition and subtraction with negative numbers?
5. What is the difference between decimal and whole number operations?

Tip: When dealing with decimals, always align the decimal points for accurate addition or subtraction.
