Hi there!

This question isn't too hard.

To add with single digit numbers you just need to count.

You can regroup too, depending on what numbers you're using. I can give you some examples if you'd like!

1 + 2 = 3 because you need to just count. If I have one apple and you have two, count to see how many apples we have altogether. In this case, we have three apples.

What about 9 + 9? You would regroup because our answer is bigger than ten. If I have nine pennies and you have nine pennies, and we put them all together you'd have 18. Just count like before ^

Hope this helps!

Answer:

14 and 16.

Step-by-step explanation:

We know that two consecutive even numbers is 30.

Let's let n be any number.

Then the first even number must be 2n.

This is because n can be any number, either even or odd. However, if we multiply it by 2, this ensures that 2n is even. Remember that any number multiplied by 2 yields an even number.

Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.

We know that they sum to 30. So, we can write the following equation.

$(2n)+(2n+2)=30$
