• i would be even because there is every alternate odd/ even so if 1 is odd then, 0 is even
• can you help me with adding fractions?
• Ok what’s the question
(1 vote)
• it said that sea monsters are nearby the lake and the question asks how many are in the lake not "nearby the lake", just saying
• It says the lake is nearby not the sea monsters nearby.
The lake could be near a house, possibly.
• Is Zero netural or is it just me?
• It comes in whole numbers
• What does this mean
• this mean the first maths that u ackowledged in your life
• If the sum of 3 consecutive numbers is 213, what are the numbers?
• Well if the three numbers are consecutive, then we start with some number, which we can call blank. The next number will be blank + 1, and the third number will be blank + 2, since they're consecutive. Then we know the sum will be:

blank + (blank + 1) + (blank + 2) = 213

So how many of our blank number do we have in total? We have three of them, it's like we're multiplying that number by three. We can write:

3*blank + 1 + 2 = 213

Which means that 3*blank = 210. You might not know 210 divided by 3 off the top of your head, but you can know that it's the same as 10 times 21 divided by 3, and 21 divided by 3 is 7. So our blank number is 10 * 7 which is 70.

Let's double check. The three consecutive number must be:

70 + 71 + 72. Add them up and what do you get? The answer is 213.
