Calculate mean, median, mode, standard deviation, variance and more — step by step.

Data

Answer

80.03

80 − -310 × .5 × .2

Step 1 — Multiply first

80 − -3/10 × .5 × .2

Convert decimal to fraction:

.5 = 12

Multiply numerators and denominators:

-310 × 12 = -3×110×2 = -320

Step 2 — Multiply first

80 − -3/20 × .2

Convert decimal to fraction:

.2 = 15

Multiply numerators and denominators:

-320 × 15 = -3×120×5 = -3100

Step 3 — Subtract (convert to common denominator)

  80.00
− -0.03
───────
  80.03

Subtract column by column (with borrowing):

Hundredths: 0 < 3 → borrow → 10 − 3 = 7

Tenths: -1 < 0 → borrow → 9 − 0 = 9

Ones: -1 < 0 → borrow → 9 − 0 = 9

Tens: 8 − 1 (borrow) − 0 = 7

80 − -0.03 = 80.03

= 80.03
