Multiplication is one of the four basic operations in arithmetic, along with addition, subtraction, and division. Multiplication can actually be considered repeated addition, and you can solve simple multiplication problems by adding repeatedly. For larger numbers, you'll want to do long multiplication, which breaks the process down into repeated simple multiplication and addition problems. You can also try a shortcut version of long multiplication by splitting the smaller number in the problem into tens and ones, but this works best when the smaller number is between 10 and 19.
<u>Restate the problem as an addition problem. </u>
<u>Add the repeated number together to get your answer. </u>
<u>Switch to long multiplication when multiplying 2-digit or larger numbers.</u>
Multiplying is basically adding the same number a certain amount of times. So if it was 4 x 3 you could add 4 + 4 + 4 and that equals 12. You can also flip it, so you could add 3 + 3 + 3 + 3 and that also equals 12. Another example is 5 x 5 you can add 5, 5 times. So it would look like 5 + 5 + 5 + 5 + 5 which equals 25.
However, when it's a number times 1 (ex: 3 x 1) it equals itself. So even if it was 4 x 1 it would equal 4. When it's a number times 0 (ex: 3 x 0) it equals zero, always.
The sign of the term in x^2 is negative so the graph will open downwards. when x = 0 y = 1 The coordinates of the vertex are (0,1) the maximum value of the function is 1 and the axis of symmetry ix x = 0 ( the y axis)
