✔ 最佳答案
(－４）＋｛－１１＋［１０－（－９）］－［（－３）＋２］｝ ＝ (－４）＋｛－１１＋［１０－（－９）］－［－１］｝
＝ (－４）＋｛－１１＋［１０＋９］＋１｝
＝ (－４）＋｛－１１＋１９＋１｝
＝ (－４）＋ ９
＝ ５

(-4)+[-11+(19)+1]
=-4+(-11+19+1)
=-4+9
=5
=-4+(-11+19+1)
=-4+9
=5

（－４）＋﹛－１１＋［１０－（－９）］－［（－３）＋２］｝
＝（－４）＋〔－１１＋（１０＋９）〕－（－１）
＝（－４）＋（－１１＋１９）＋１
＝（－４）＋８＋１
＝５
多謝
＝（－４）＋〔－１１＋（１０＋９）〕－（－１）
＝（－４）＋（－１１＋１９）＋１

(-4)+{-11+ -1 - 1}
=(-4)+(-9)
=-13
好易計姐
正負數加or -既口記
正正得正
負負得正
正負得負
負正得負
背熟左學負正數既四則就易好d
岩岩學 d老師都會教你用數線 好易明架炸
=(-4)+(-9)

i think is :
=（－４）＋｛－１１＋［１０－（－９）］－［（－３）＋２］｝
= （－４）＋｛－１１＋［19］－［-1］｝
= （－４）＋｛-11+19+1｝
= （－４）＋｛9｝
=5
^ , ~
=（－４）＋｛－１１＋［１０－（－９）］－［（－３）＋２］｝
= （－４）＋｛－１１＋［19］－［-1］｝
= （－４）＋｛-11+19+1｝
= （－４）＋｛9｝
=5

= =
（－４）＋｛－１１＋［１０－（－９）］－［（－３）＋２］｝
= -4+ [-11 +10+9+1]
=5
（－４）＋｛－１１＋［１０－（－９）］－［（－３）＋２］｝
= -4+ [-11 +10+9+1]
=5
