This is one you should know, right alongside 10 x 10 and 11 x 11. If you don't know it off the top of your head, all you need to do is multiply and remember to bring that zero down to your second line.

1. 76x + 16y - 18
   21x + 77y - 14
2. 49x + 16y + 24
   56x + 82y - 18

Simplifying this problem would require you to use the order of operations, PEMDAS. You'd first need to distribute the negative sign across the middle parentheses and then multiply the 7 across each factor.

1. y = 7
   y = -7
2. y = 11
   y = 5

When solving for variables, you'd first have to add the 35 to both sides of the equation. You'd then solve for y by dividing.

64 is a perfect square meaning that there is a number, when multiplied by itself, gives you 64. This is the case for the number 8, so when 64 is divided by 8, the answer is 8.

When dealing with exponents and multiplication, all you have to do is keep the base and add the exponents. This would make the x stay the same, and the exponent would become 4.

1. 14x + 9x + 15
   14x^2 -11x - 15
2. 12x^2 + 16x - 15
   None of the above

When multiplying polynomials, oftentimes you only have to look at the first and last variables in the problem. 7x multiplied by 2x would give you 14x^2. 5x multipled by negative 3 would give you NEGATIVE 15. There is only one answer with these variables.

The number 5 falls between the square roots of 24 and 26. Since 25 is a perfect square and would give you 5 if you were to take the square root, you can be sure that 5 falls within these surrounding numbers.

When solving a problem like this, you can first pretend that the decimals aren't even there! Once you solve it, remember to go back in and place them. Since both numbers have one digit after the decimal, your answer should have TWO digits after the decimal.

1. 1/2
2. 2/3

When dealing with fraction, you'd have to set them with the same denominator to find out which is bigger. Since 6 is the LCM, you would multiply 1/2 by 3/3 and 2/3 by 2/2 to compare them and figure out that 2/3 is bigger.

In a deck of cards, you'd first half to remember that there are 52 cards in the deck and that half of them are red. That means, you have a 26/52 chance that the first card you draw will be red. This simplifies down to 1/2.

When changing an equation into standard form, the exponent tells you how many places to move the decimal. Since this problem has 3 as the exponent, there should be be 3 numbers following the 4.

When it comes to dividing decimals, all you need to do is divide regularly, but remembering to place the decimal moves straight up from the dividend.

   7.01 x 10^3
2. 7.01 x 10^2
   7.01 x 10^5

When dealing with scientific notation, the exponent tells you how many places there are before or after the decimal. Since there are four spaces after the 7, this means that the proper scientific notation would have to have the decimal placed after the 7 and a 4 as the exponent.

One hundred thirty nine is not a perfect square. The other answers are! Thirty-six is the perfect square of 6, One hundred sixty nine is the perfect square of 13, and 256 is the perfect square of 16.

When dealing with negative exponents, you can move the number to the numerator or denominator to make it positive or negative. In this problem, you can move the (3^-2) to the denominator to make it become (3^2). The same could be said for (2^-3). This would make the answer 8/9.
