WORKSHEET # 1 Absolute Value & Integer Review
Find the absolute value for each expression. Show ALL support work when necessary! 1) 9 = ________ 2) − 23 = ________ 3) − −7 = ________ 4) 18− 22 = ________ 5) 10− 6 = ________ 6) 5 − 3− 4 = ________ Let’s Level Up!!! (Review Integers and OOO using absolute value!) Treat the absolute value bars like you would “parentheses”. Follow OOO inside the absolute value bars BEFORE you take the absolute value! Have fun, you got this!!! J I will walk you through the first few, then it’s all you! 7) 3+ 2 4− 1 = ________ 8) 5+ (−3)! 1− 2 • 2 = ________ 3+ 2 _______ = ________ 5+ ______ 1− _____ = ________ 3+ ________ = ________ 5+ _______ _____ = ________ 9) 9÷ 3+ 2− 5− (2− 7) = ________ 10) 2 • 9÷ 3+ 8! − 4 4− 2 • 5 = ________
** BONUS ** −2! + 4 • 5 − 7 − 8 + !! ! !" !!
= ________ (optional, but try it!)
Fill in the Blank: 11) Absolute value is the __________________________________ from zero. 12) Absolute value is always a ___________________________________ number. 13) An integer is any positive or negative _____________________ number, and zero too! 14) ______ + 5 = 15 15) 12 ÷ ______ = 4 16) 9 • _______ = 54 18) 3 + 7 – 6 + _________ = 13 19) 4 • 3 • 2 • _________ = 24 20) 2( _______) + 8 = 28
