Grammar:
I learned about the two parts of a sentence. There is a subject, which is what the sentence is about, and the predicate, which is what we are saying about the subject. My mom wrote out sentences that I had to cut where the subect ends and the predicate starts. You need to be careful because a subject isn't the first word or so. It can be be really long, about half of the sentence sometimes. I got them all right!
Pre-Algebra:
I moved into harder exponents after learning squares. I learned to add, subtract, multiply, and divide integers with exponents. Here are the rules I learned:
Definition: Let a be any number and let n be a positive integer. The power a^n, pronounced “a to the n,” is defined by the equation
A^n = a * a * … * a.
|
V
N copies of a
For example, a^5 = a * a * a * a * a
Important: let a and b be numbers. Let n be a positive integer
Power of product: (a*b)^n = a^n*b^n
Power of reciprocal: if b is nonzero, then (1/b)^n = 1/b^n
Power of quotient: If b is nonzero, then (a divided by b)^n = a^n divided by b^n
WARNING!! Suppose a and b are nonzero numbers, and n is an integer greater than 2. Just as (a + b)^2 is not equal to a^2 + b^2, the expression (a + b)^n is not necessarily equal to a^n + b^n.
Important: Cube of negation: Let a b any number. Then
(-a)^3 = -a^3
Important: Power of negation: Let a be any number. Let n be a positive integer. If n is even, then (-a)^n = a^n if n is odd, then (-a)^n = -a^n.
Important: Product of powers (same base): Let a be any number. Let m and n be positive integers. Then
A^m · a^n = a^m+n.
Quotent of powers (same base): Let a be a nonzero number. Let m and n be positive integers such that m is greater than n. then
A^m divided by a^n = a^m–n
Important: Power of power: Let a be any number. Let m and n be positive integers. Then
(a^m)^n = a^mn
Ancient Civilization:
I learned how to make peasant girdle bread this time. I thought it was pretty good with butter. Grama Tina liked hers with jam. Here is the recipe for you to try:
Ingredients
- a cup of warmed ale
- wholemeal flour
- an egg
- Bolt the flour through a cloth, to make the flour white (this makes manchet (white) bread)
- Add the warmed ale – the yeast in this will make the bread rise. Mix to make a dough
- Into the centre of the dough, add the egg and fold this into the dough
- On a floured board, knead half of the dough into a flat circle
- Repeat with the rest of the dough
- Set a griddle pan on the fire to heat. When it is hot put a piece of fat in and coat the pan
- Place one bread in at a time a cook. The bread will need to be turned from time to time to stop it burning
- Wrap the cooked breads in a clean cloth to keep warm while the rest cook
- When they are all cooked, serve hot
love your pictures!! The bread didn’t look as yummy as the soup! So glad we have sliced bread now:)

i must admit I lost you on all the n^s and a*s and putting it all together to make a problem! I forgot, and tHis reminded me, That algebra is really a language rather than a math in many ways! Good job on all your work! I must remember not to play “Are You Smarter Than a Fifth Grader” with you, because I know I have forgotten all of that and know I am not! God job Sage! I am impressed! And you can cook too! Chemistry should be right up your ally!

Sage, you won’t remember me but I want to tell you that you are so far ahead of your years. I know everyone is so proud of you. Keep learning all you can. God Bless you. You are such a handsome young man.
