long addition

3.5 + 4.5

8

Solution steps

3.5 + 4.5

Write the numbers one under the other, line up the decimal points.

Add trailing zeroes so the numbers have the same length.

+ 34 . . 55

Add each column of digits, starting on the right and working left.

If the sum of a column is more than ten, 'carry' digits to the next column on the left.

Add the digits of the bolded column:

5 + 5 = 10

+ 34 . . 55

Carry

1

to the column on the left and write

0

in the bolded column

\frac{+ 1 3 4 . . 5 5}{+ 0}

Place the decimal point in the answer directly below the decimal points in the terms

\frac{+ 1 3 4 . . 5 5}{+ . 0}

Add the digits of the bolded column:

1 + 3 + 4 = 8

\frac{+ 1 3 4 . . 5 5}{+ 8 . 0}

= 8

- 3 + 10

(\frac{2 x ^{3} y ^{2}}{- x ^{2} y ^{5}})^{- 2}

5 (3 x - x + 8) + 4 x = 41 + 15 x

\frac{3}{4 x} - 6 \leq x - 7

\frac{12 !}{0 ! 12 !} (0.36)^{12} (0.64)^{0}
