Challenge!!20 - 3 • 6 + 102 + (6 + 1) • 4
= 20 - 3 • 6 + 102 + (7) • 4(parentheses)
= 20 - 3 • 6 + 100 + (7) • 4(exponents)
= 20 - 18 + 100 + (7) • 4 (Multiply l/r.)
= 20 - 18 + 100 + 28 (Multiply l/r.)
= 2 + 100 + 28 (Subtract l/r.)
= 102 + 28 (Add l/r.)
= 130 (Add.)
Skills Check!When you finish turn your paper
